伏者，毒蓄于里而不出也。陷者，毒出而复陷入也。此皆恶候。伏唯一证，陷有数种，伏候于见形之时，其人疮出，
热不少减，烦渴闷躁，此有伏毒未得尽出也。陷则见形之后，其血渐干而变黑者，谓之黑陷。浆水未成破损痒塌者，
谓之倒陷。脓成复化为水，不肯结痂者，谓之倒靥，亦陷类也。其疮黑色，皆谓之黑陷，凡
疹黑色，皆不治之，以肾为水，其黑色，乃肾之真脏色见也，粗工不知变黑归肾之理，妄谓肾不可实，欲泻肾而使之
虚，不知人之一身，大言阴与阳，小言心与肾，即方家所谓真水真火也，疮疹之火发于中，赖此一点真水、以制其
充，苟欲泻之，则火无所制，本先拨矣，岂治之要哉。然谓归肾者，以肾主骨髓，又主闭藏也，盖疮疹秽毒，由骨
髓达于筋肉皮毛之间，乃自内而外，其毒得泄，今既陷伏，则自外而复入于内，藏于骨髓，谓之归肾也。又初出形之时，
春气发生之令也，出形而黑，是春行冬令矣。起壮之时，夏气长养之令也，起发而黑，是夏行冬令矣。养浆之时，
秋气成实之令也，脓干而黑，是秋行冬令矣。故皆谓之逆。结 之时，冬气闭藏之令也，此肾之正候，若不着痂，脓
水浸润，此冬行春夏之令，亦谓之逆。惟知造化之机，可以语归肾之说，其色黑者，火化也，观物之干者其色黑，出
于火者色亦黑，岂可谓之水乎。经曰∶火发而熏昧。知此，可以语黑陷矣。
凡疮伏而不出者，双解散主之（初热）。 点色白或黑色，其人必不能食乳，大便自利，或呕或厥，此胃虚弱
而不能副荣卫故也，宜用温中之剂，令其胃暖，荣卫复行，则当自出矣，宜理中汤（痘吐利）丁香煮散（痘吐逆）之类。
如倒陷者，看其大腑何如，如大小便秘，四顺清凉饮（发热）合夺命丹（见形）主之。泄利气弱者，十全大补汤
（汗）合夺命丹主之。并外用胡荽酒、水杨汤（俱起发）。丹溪先生云∶痘疮倒陷，因真气虚而毒瓦斯不能尽出者，用
黄、人参、紫草酒制治之。若将成就之际却淡色者，属血虚，用当归、川芎之类，或加红花、紫草。属热毒者，
用升麻、芩、连、梗、翘之类，甚者用犀角屑，大解痘毒。〔薛〕窃谓前证若热毒方出，忽被风寒闭塞肌窍，血脉不行，
身体作痛，或四肢微厥， 点不长，或变青紫黑色者，此为倒靥。若胃气虚弱，不能补接荣卫，出而复没者，谓之陷
伏。误用解毒之药，必致陷塌。若喜热饮食，手足并冷者，乃脾胃亏损，阳气虚寒之证，宜用辛热之剂补之。喜冷冻饮料
食，手足并热，乃阳气实热之证，宜用苦寒之剂泻之。外感风寒者，温散之。毒入腹者，分利之。阳气虚者，温补之。
外寒触犯者，熏解之。自昔谓白陷不可救，盖痘色白者，必变为灰惨，灰惨者，必至于平伏倒塌，故谓之白陷，此固由
气虚所致，然血不华色，血亦本虚，治法须兼气血为当，血活气行，白可变而为红，自不至于陷塌矣。若单补气，则气
愈燥热，势必陷伏，故白陷抓破，皮薄干燥而极痒者，由失于补血，致气盛极而燥也，愈用补气之药，速死之兆也。
故凡见痘色白者，无分先后，皆以补中益气汤合四物汤治之，内有热者，加解毒药，或利小便，若待白陷已成，而后
治之，难为力矣。痘有紫黑陷，灰白陷。紫黑陷者，乃血热干滞，而气亦不能以营运，有余之证也，急治之，犹
多可活。灰白之陷，乃元气衰败，故不能起发，而血亦不得通贯，不足之证也，多难救治。
如将起发，疮亦有水，但色黑黯者，以十全大补汤（汗）调无价散主之，或以快 汤（见形）、夺命丹（见形）
合而服之。
如倒靥者，亦视其大便何如。大便秘，宜利之，三黄丸、四顺清凉饮（俱发热）。泄利者，宜补之，轻则十全
大补汤，甚则陈氏木香散（泻），并外用败草散（收靥）主之。

伏，是指毒邪蕴结于体内而不能透发出来。陷，是指毒邪虽然透出体表，随后又陷入体内。这两种情况都属于危重的证候。伏证只有一种表现，而陷证有多种类型。伏证的征象出现在痘疹显现形态的时候，此时患者身上发出痘疮，但发热并没有明显减轻，反而出现烦躁、口渴、胸闷和躁动不安，这说明有伏留的毒邪未能完全透发出来。陷证则发生在痘疹显现形态之后，如果痘疮的血浆逐渐干枯并变成黑色，这叫做“黑陷”。如果痘浆尚未形成就破损、瘙痒且塌陷，这叫做“倒陷”。如果脓液已经形成却又化为水样液体，不肯结痂，这叫做“倒靥”，这也属于陷证的范畴。凡是痘疮呈现黑色的，都称为黑陷。凡是痘疹变黑的，都属于不治之症，因为肾属水，其对应的颜色是黑色，这是肾的真脏色外露的表现。粗劣的医生不懂得“变黑归肾”的道理，错误地认为肾不可用补法（实则指不可使肾气过盛），想要通过泻法使肾气虚弱，却不知道人体一身，大而言之是阴与阳，小而言之是心与肾，也就是方书中所说的真水和真火。痘疹的火毒发源于体内，依赖这一点点真水来制约其亢盛，如果试图去泻它，那么火毒就失去了制约，根本就会动摇，这哪里是治疗的要领呢？然而说毒邪“归肾”，是因为肾主骨髓，又主闭藏。痘疹的秽浊毒邪，是由骨髓通达于筋肉皮毛之间，这是由内向外，毒邪得以宣泄；现在既然陷入伏留，则是从外再次向内，藏匿于骨髓之中，所以称之为“归肾”。另外，在痘疹初出形态的时候，正值春季生发之气的主令，如果出形后变黑，这是春季行冬季的肃杀之令。在起壮（高热）的时候，正值夏季长养之气的主令，如果起发时变黑，这是夏季行冬季的肃杀之令。在养浆（灌浆）的时候，正值秋季成实之气的主令，如果脓干后变黑，这是秋季行冬季的肃杀之令。所以这些都称为逆证。在结痂的时候，正值冬季闭藏之气的主令，这是肾脏的正常征候，如果不结痂，脓水浸润，这是冬季行春夏的生发之令，也称为逆证。只有懂得自然造化机理的人，才可以谈论“归肾”的说法。那些颜色发黑的，属于火化现象，观察物体被火烧干后的颜色是黑的，从火中出来的东西颜色也是黑的，怎么能说是水呢？《内经》说：“火气发动而熏灼昏暗。”懂得这个道理，就可以谈论黑陷了。
凡是痘毒伏留而不能透发的，用双解散主治（适用于初热阶段）。如果痘点颜色白或黑，患者必然不能吃奶，大便自利（腹泻），或者呕吐或者四肢厥冷，这是因为胃气虚弱，不能配合荣卫之气运行所致，适宜使用温中的药剂，使胃气温暖，荣卫之气恢复运行，痘疹自然就会透发出来，适宜用理中汤（治疗痘疹呕吐腹泻）、丁香煮散（治疗痘疹呕吐逆乱）之类的方剂。如果是倒陷的情况，要看患者的大便情况如何，如果大小便便秘，用四顺清凉饮（治疗发热）合夺命丹（适用于见形阶段）主治。如果腹泻、气虚体弱，用十全大补汤（适用于汗出阶段）合夺命丹主治。同时外用胡荽酒、水杨汤（均用于起发阶段）。丹溪先生说：痘疮倒陷，是因为真气虚弱而毒瓦斯不能完全透发出来，用黄芩、人参、紫草（酒制）来治疗。如果痘疮即将成熟时颜色却淡白，属于血虚，用当归、川芎之类的药物，或者加红花、紫草。属于热毒的，用升麻、黄芩、黄连、桔梗、连翘之类的药物，严重的用犀角屑，以解除痘毒。〔薛己〕私下认为前面的证候，如果是热毒刚刚发出，忽然被风寒闭塞肌窍，血脉不通，身体疼痛，或者四肢轻微厥冷，痘点不长，或者变为青紫黑色，这叫倒靥。如果胃气虚弱，不能补充接续荣卫之气，痘疹透出后又隐没下去，这叫陷伏。误用解毒的药物，必然导致塌陷。如果喜欢热饮食，手足都冷的，是脾胃亏损，阳气虚寒的证候，适宜用辛热的药剂来补益。喜欢冷冻饮料食物，手足都热的，是阳气实热的证候，适宜用苦寒的药剂来清泻。外感风寒的，用温散的方法。毒邪入腹的，用分利小便的方法。阳气虚的，用温补的方法。外寒触犯的，用熏解的方法。自古以来认为白陷不可救，大概痘色白的，必然变为灰惨色，灰惨色的，必然至于平伏倒塌，所以叫白陷，这固然由气虚所致，但是血不华色，血也本虚，治法必须兼顾气血才恰当，血活气行，白色可以变为红色，自然不至于陷塌了。如果单补气，则气更加燥热，势必陷伏，所以白陷被抓破，皮薄干燥而且极痒的，是由于失于补血，导致气盛极而燥，越用补气的药，是速死的征兆。所以凡是见到痘色白的，无论先后，都用补中益气汤合四物汤治疗，内有热的，加解毒药，或者利小便，如果等到白陷已成，然后再治疗，就很难起作用了。痘疹有紫黑陷、灰白陷。紫黑陷的，是血热干滞，而气也不能营运，属于有余的实证，急治的话，大多可以存活。灰白的陷，是元气衰败，所以不能起发，而血也不能通贯，属于不足的虚证，大多难以救治。
如果将要起发，痘疮也有水，但颜色黑黯的，用十全大补汤（适用于汗出阶段）调无价散主治，或者用快斑汤（适用于见形阶段）、夺命丹（适用于见形阶段）合起来服用。
如果是倒靥，也要看其大便情况如何。大便便秘的，宜通利，用三黄丸、四顺清凉饮（均用于发热阶段）。腹泻的，宜补益，轻则用十全大补汤，重则用陈氏木香散（用于泻痢），并外用败草散（用于收靥）主治。
〔庞安常〕郁金散：治疗痘疮起初有白泡，忽然搐入腹中，渐渐变成紫黑色，无脓，日夜啼叫，烦乱不安的。
郁金（一枚） 甘草（一分）
用水半碗，煮至水干，去掉甘草，切片，焙干，研为细末。加入脑子（冰片）半钱，同研一钱匕，用生猪血五七滴，新汲水调服。不超过两服，严重的毒瓦斯会从手足心排出，状如痈肿，这才是痊愈，这是五死一生的危重证候。
四圣散：治疗黑陷倒靥，不起发，不红活，小便不利的。
紫草 黄芪 甘草 木通
以上药材，水煎服。热甚色紫的，加倍加紫草、黄芩、黄连、红花。大便秘结的，加枳壳。如常的，加糯米。

《罗浮方》治疗塌陷痘。歌诀说：乌蛇、全蝎与僵蚕，带肉穿山甲与缠（指某种草药或部位，此处依原文保留），四样净该均一两，绵官桂倍加焉，白酒煮浓随意服，见多陷痘得回全。我每次使用此方，保全了很多生命，但僵蚕必须去丝，清水洗去锻石，再晒干，乌蛇必须用尾部极好的，穿山甲先酒洗，焙干使用。
〔袁氏〕治疗倒靥。歌诀说：倒靥原为痘后难，只因气血两相残，参、芪、归、地并蝉蜕，连绵进服靥自还。又说：倒靥血不止，名为回阳泉，若犯胸胁地，十来九不全，速觅胭脂胚，血竭加一钱，烧之俱存性，点上血收干。我看见痘后倒靥，很多人妄用浴法，枉杀人命男女。如果痘后结痂脓垒堆积，不能脱起，或者半脱而半在，或者四周围脱而中心锥痛，准用后方。
生蜜 苏合油
这两味药调匀。用银簪敷在痘盘边缘处，疼痛立即停止，而痘痂自然快速脱落，没有呛血刨肉的祸患，如果没有苏合油，只用线鸡油代替，也很妙。
Fu (entrapment) refers to the pathogenic toxin accumulating internally without being able to emerge. Xian (sinking) refers to the pathogenic toxin emerging but subsequently sinking back inward. Both are ominous signs. Fu presents as a single syndrome, whereas Xian has several types. The signs of Fu appear when the lesions manifest; at this time, the patient develops sores, yet the fever does not significantly decrease, accompanied by irritability, thirst, chest stuffiness, and restlessness. This indicates that latent toxins have not been fully expelled. Xian occurs after the lesions have manifested. If the fluid within the sores gradually dries up and turns black, it is called "Black Sinking" (Hei Xian). If the pustules rupture, itch, and collapse before forming properly, it is called "Inverted Sinking" (Dao Xian). If pus forms but then reverts to water-like fluid and fails to scab over, it is called "Inverted Scabbing" (Dao Ye), which also belongs to the category of sinking syndromes. Any sore presenting with black coloration is termed Black Sinking. All rashes turning black are considered intractable because the Kidney corresponds to Water, and its associated color is black; thus, blackness represents the revelation of the true organ color of the Kidney. Incompetent physicians fail to understand the principle of "blackness returning to the Kidney." They erroneously believe that the Kidney should not be tonified (in the sense of avoiding excess) and attempt to drain the Kidney to induce deficiency. They do not realize that the human body, broadly speaking, consists of Yin and Yang, and specifically, the Heart and Kidney—what medical texts refer to as True Water and True Fire. The fire-toxin of rashes originates internally and relies on this trace of True Water to restrain its hyperactivity. If one attempts to drain it, the fire-toxin loses its restraint, and the root foundation is undermined. How can this be the essence of treatment? However, saying the toxin "returns to the Kidney" is because the Kidney governs bone marrow and closure/storage. The filth and toxin of rashes travel from the bone marrow to the muscles, skin, and hair, moving from inside out, allowing the toxin to be vented. Now, having sunk and entrapped, it moves from outside back inside, hiding in the bone marrow; hence it is called "returning to the Kidney." Furthermore, when rashes first manifest, it is the season of Spring, governed by the generating Qi. If they turn black upon emergence, it is Winter's command acting in Spring. During the stage of rising fever (Qi Zhuang), it is Summer, governed by the nurturing Qi. If they turn black during eruption, it is Winter's command acting in Summer. During the stage of nourishing pus (Yang Jiang), it is Autumn, governed by the solidifying Qi. If the dried pus turns black, it is Winter's command acting in Autumn. Therefore, all these are termed adverse conditions. During the scabbing stage, it is Winter, governed by the storing Qi; this is the normal state of the Kidney. If no scab forms and pus infiltrates, it is Spring/Summer's command acting in Winter, also termed adverse. Only those who understand the mechanisms of natural transformation can discuss the theory of "returning to the Kidney." The color black relates to Fire transformation; observing that objects burned dry turn black, and things emerging from fire are black, how can one claim this is Water? The Classics state: "When Fire activates, it causes smoldering and obscurity." Understanding this allows one to discuss Black Sinking.
For cases where rash toxins are entrapped and fail to emerge, Shuangjie San (Double Resolution Decoction) is the primary formula (for initial heat stages). If the spots are white or black, the patient will likely refuse milk, experience spontaneous diarrhea, vomiting, or cold limbs. This is due to Stomach Qi deficiency failing to support Ying and Wei (Nutritive and Defensive Qi). It is appropriate to use warming Middle Jiao agents to warm the Stomach; once Ying and Wei circulation resumes, the rash will naturally emerge. Suitable formulas include Lizhong Tang (Regulate the Middle Decoction for vomiting/diarrhea in smallpox) and Dingxiang Zhusan (Clove Boiled Powder for vomiting/reversal in smallpox). For inverted sinking, assess the bowels. If constipated, Sishun Qingliang Yin (Four Compliance Cooling Drink for fever) combined with Duoming Dan (Life-Restoring Pill for manifestation stage) is indicated. If there is diarrhea and weak Qi, Shiquan Dabu Tang (Ten Thousand Benefits Decoction for sweating stage) combined with Duoming Dan is indicated. Externally, apply Huisu Jiu (Coriander Wine) and Shuiyang Tang (Water Poplar Decoction, both for eruption stages). Master Danxi stated: Inverted sinking of smallpox is caused by deficiency of True Qi preventing complete expulsion of toxins; treat with Huangqin (Scutellariae Radix), Renshen (Ginseng Radix), and Zicao (Arnebiae Radix) prepared with wine. If the lesions become pale just before maturation, it belongs to Blood deficiency; use Danggui (Angelicae Sinensis Radix) and Chuanxiong (Ligustici Chuanxiong Rhizoma), possibly adding Honghua (Carthami Flos) and Zicao. If belonging to Heat-Toxin, use Shengma (Cimicifugae Rhizoma), Huangqin (Scutellariae Radix), Lianlian (Coptidis Rhizoma), Jiegeng (Platycodonis Radix), and Qiaoyao (Forsythiae Fructus). For severe cases, use Xijiao Xie (Rhinocerontis Cornu Fragmenta) to resolve large amounts of toxin. [Xue Ji] privately opines that if Heat-Toxin is just emerging but suddenly blocked by Wind-Cold closing the muscle pores, causing blood stasis, body pain, slight limb coldness, failure of spots to grow, or turning cyanotic/black/purple, this is Dao Ye (Inverted Scabbing). If Stomach Qi is weak and cannot supplement Ying and Wei, causing the rash to emerge and then vanish, this is Xian Fu (Sinking Entrapment). Misusing detoxifying herbs will inevitably lead to collapse. If the patient prefers hot drinks and has cold hands and feet, it is a syndrome of Spleen-Stomach damage with Yang Qi deficiency and Cold; treat with acrid-hot tonics. If the patient prefers cold drinks and has hot hands and feet, it is a syndrome of excessive Yang Heat; treat with bitter-cold purgatives. For external Wind-Cold, use warming dispersal. For toxins entering the abdomen, use separating and draining methods. For Yang Qi deficiency, use warming tonification. For external Cold invasion, use fumigation and resolution. Historically, it was said that White Sinking is incurable. Generally, white spots turn gray and miserable; gray and miserable spots flatten and collapse, hence called White Sinking. This is indeed caused by Qi deficiency, but since Blood fails to provide luster, Blood is also fundamentally deficient. Treatment must address both Qi and Blood. When Blood circulates and Qi moves, white can turn red, preventing sinking. If only Qi is tonified, Qi becomes overly dry and hot, inevitably leading to sinking. Thus, if white sinking is scratched, with thin, dry, intensely itchy skin, it results from neglecting Blood tonification, leading to extreme Qi excess and dryness. Using more Qi-tonifying herbs is a sign of imminent death. Therefore, for any white spots, regardless of timing, use Buzhong Yiqi Tang (Tonify the Middle and Augment the Qi Decoction) combined with Siwu Tang (Four Substances Decoction). If internal heat exists, add detoxifying herbs or promote urination. If treatment is delayed until White Sinking is established, it is difficult to effect a cure. Smallpox presents with Purple-Black Sinking and Gray-White Sinking. Purple-Black Sinking is due to Blood Heat causing stagnation, with Qi unable to circulate; this is an excess syndrome. If treated urgently, survival is likely. Gray-White Sinking is due to exhaustion of Yuan Qi (Primal Qi), preventing eruption and Blood penetration; this is a deficiency syndrome, often difficult to save.
If eruption is impending and sores contain fluid but are dark black, use Shiquan Dabu Tang (Ten Thousand Benefits Decoction) to administer Wuji San (Priceless Powder). Alternatively, combine Kuaiban Tang (Rapid Eruption Decoction) and Duoming Dan (Life-Restoring Pill).
For inverted scabbing, again assess the bowels. If constipated, promote unblocking with Sanhuang Wan (Three Yellows Pill) or Sishun Qingliang Yin (Four Compliance Cooling Drink). If diarrheic, tonify with Shiquan Dabu Tang (mild cases) or Chen's Muxiang San (Chen's Costus Powder for severe cases), externally applying Baicao San (Decayed Grass Powder).
[Pang Anchang] Yujin San (Curcuma Powder): For smallpox starting with white blisters, suddenly retracting into the abdomen, gradually turning purple-black, lacking pus, with day-and-night crying and agitation.
Yujin (Curcumae Radix, 1 piece) Gancao (Licorice Root, 1 fen)
Boil in half a bowl of water until dry. Remove Gancao, slice, bake dry, and grind to fine powder. Add Naozi (Borneolum Syntheticum, half qian), mix with 1 qian of powder. Take with 5-7 drops of fresh pig blood, mixed with fresh well water. Within two doses, severe toxins will exit via the palms and soles like boils, indicating recovery. This is a critical condition with five deaths to one life.
Sisheng San (Four Sages Powder): For black sinking, inverted scabbing, lack of eruption, non-vibrant color, and difficult urination.
Zicao (Arnebiae Radix) Huangqi (Astragali Radix) Gancao (Licorice Root) Mutong (Akebiae Caulis)
Decoct in water and drink. If heat is severe and color purple, double Zicao, add Huangqin (Scutellariae Radix), Lianlian (Coptidis Rhizoma), and Honghua (Carthami Flos). If constipated, add Zhike (Aurantii Fructus). If normal, add Nuomi (Oryza Sativa Glutinosa).
Shenneituo San (Ginseng Internal Support Decoction - see Itching/Collapse section)
Wuji San (Priceless Powder)
Use human, cat, pig, and dog feces, burned to ash in the twelfth lunar month. Mix with rock sugar water and take.
Nanjin San (Southern Gold Powder): Treats rashes that emerge and then sink, a critical condition unresponsive to other drugs, ensuring safety.
Zibei Heye (Purple-backed Lotus Leaf, harvested after frost) Baijiangcan (White Silkworm, washed free of silk, stir-fried dry)
Grind to powder. Equal parts. Dosage depends on age: adults 1 qian, children 0.5 qian. Grind with Yuanxu juice (Coriander juice) and wine, or rice water.
Treating this condition often involves Longnao (Borneolum) and Renya (Human Teeth), which are hard to obtain. This formula is non-toxic and fast-acting. Purple-backed leaves are rare; check salt shops.
Golan Yin (Olive Drink): Treats inverted scabbing.
Cut olives in half. Take a small amount with water. Eruption occurs immediately.
Baihuashe San (White-Banded Snake Powder): Treats smallpox/rash black sinking and inverted scabbing.
Baihuashe (Bungarus multicinctus, including bones, 1 liang, fire-dried but not burnt) Dingxiang (Caryophylli Flos, 20 pieces)
Grind to powder. Take 0.5 qian or 0.2 qian with hot wine. For black sinking, if color turns red after a while, it is very effective.
*Luofu Fang* (Luofu Formula) for collapsed smallpox. Verse:
"Wu She (Bungarus multicinctus), Quanxie (Scorpio), and Jiangcan (Silkworm),
Along with Shan Jia (Pangolin scales) with meat attached.
Take one liang of each purified ingredient,
Add twice the amount of Guan Gui (Cinnamomi Cortex).
Boil in strong white wine and drink as desired;
Many collapsed cases will recover completely."
I have used this frequently, saving many lives. Note: Jiangsan must be cleaned of silk and lime dust, then dried. Use the best tail of Wu She. Wash Shan Jia in wine and bake dry.
[Yuan Shi] Treating inverted scabbing. Verse:
"Inverted scabbing is difficult post-smallpox,
Due to mutual depletion of Qi and Blood.
Ren Shen (Ginseng), Huang Qi (Astragalus), Dang Gui (Angelica), Di Huang (Rehmannia), and Chan Tui (Cicada Slough),
Taken continuously, scabs will return naturally."
Another verse:
"If inverted scabbing bleeds incessantly, it is called 'Returning Yang Spring.'
If it affects the chest and hypochondrium, nine out of ten die.
Quickly find Yan Zhi Pei (Alkanna tinctoria embryo), add one qian of Xue Jie (Dragon's Blood).
Burn them preserving their nature, apply to stop bleeding and dry the wound."
I have seen many mistakenly use bathing methods for post-smallpox inverted scabbing, causing unnecessary deaths. If scabs pile up with pus and cannot detach, or detach partially, or detach around the edges but cause piercing pain in the center, use the following formula:
Sheng Mi (Raw Honey) Suhe You (Styrax Oil)
Mix evenly. Apply along the edge of the scab base with a silver needle. Pain stops immediately, and scabs detach quickly without bleeding or flesh damage. If Suhe You is unavailable, substitute with Ji You (Chicken Fat), which is also excellent.
