种痘的居室，最重要的是保持洁净，切忌冲犯禁忌。房间最喜明亮，不可幽暗。应选择老成持重、办事稳妥的人，且是曾经照料过小儿出过痘的人，让他们负责调护，时刻不离孩子左右。所有的禁忌事项，都应当严格遵守。不要责骂呼喝，不要言语惊慌，不要当着孩子的面梳头，不要当着孩子的面搔痒，不要嗜酒，不要唱歌奏乐。凡是房中淫液的气味，妇女经血的气味，腋下的狐臭气，长途行走后的汗气，误烧头发的气味，误烧鱼骨的气味，吹灭灯烛时产生的气味，硫磺燃烧柴草产生的烟气，葱蒜和醉酒混合的气味，沟渠中污浊的气，这些都应当避开。更应当预先嘱咐身边的人，如果遇到迅雷、烈风、暴雨等变故，非常需要安定情绪，不要让婴儿受惊，收起蚊帐时要谨慎，覆盖要严密，千万不要剧烈动作产生风。经常焚烧避秽香，以躲避偶尔出现的邪气。再让人谨慎看守门户，不许陌生人往来，也不许僧人、道士、教师、巫师以及身穿孝服的人进入室内。以上禁忌，一一遵守就会吉利，稍有疏忽，往往导致失败。种痘者务必反复告诫这一点。

The room for variolation must be the cleanest possible, strictly avoiding any violation of taboos. Brightness is preferred; darkness should be avoided. One should select an experienced and reliable person who has previously cared for children with smallpox to attend to them, never leaving their side. All prohibitions must be strictly observed. Do not scold or shout, do not speak in a panicked manner, do not comb hair in front of the child, do not scratch oneself in front of the child, do not indulge in alcohol, and do not sing or play music. One must avoid all odors present in the room, such as those from vaginal discharge, menstrual blood, axillary osmidrosis (fox odor), sweat from long-distance walking, burnt hair, burnt fish bones, extinguished lamp wicks, smoke from burning sulfur and firewood, fumes from onions, garlic, and intoxication, and foul air from ditches. Furthermore, one must instruct those around to remain calm during sudden thunderstorms, fierce winds, or heavy rain, ensuring the infant is not frightened. The mosquito net should be handled with care, and coverings should be tight; violent movements that generate wind must be strictly avoided. Incense for repelling filth should be burned regularly to ward off occasional evil qi. A guard should be posted at the door to prevent strangers from entering, and monks, Taoist priests, teachers, shamans, and mourners wearing mourning clothes are also prohibited from entering the room. If these taboos are observed one by one, good fortune will ensue; even slight negligence often leads to failure. Those performing variolation must earnestly warn against this.
Repelling Filth Incense: Rhizoma Atractylodis Chinensis (Nan Cangzhu, 南苍术) - half jin (approx. 250g); Rhizoma Rhei (Chuan Dahuang, 川大黄) - four liang (approx. 125g). Cut the herbs into fine slices and burn them in a stove without interruption.
If the infant's face is ruddy, with spirit bright and penetrating, and there is no bluish-dark discoloration at the Yintang (between eyebrows), Shangen (root of nose), Nianshou (bridge of nose), under the eyes, or at the corners of the mouth. The whites and pupils of both eyes are distinct, gaze is steady and upright, becoming more spirited and luminous the longer one looks. The fontanelle is neither sunken nor bulging. The skull sutures have not separated (jiechu). The nostrils are of normal size. The breath is clear and not turbid. The voice is clear and resonant. The Tianzhu bone (neck vertebrae) is straight, and the neck is not crooked. Flesh and bone are proportionate, the body is well-supported; if fat, flesh does not sag; if thin, bones are not prominent. Urination is distant and prolonged. The scrotum is tight and small, slightly purplish-black like the shell of a lychee. There are no eczema, tinea, sores, or scabies on the body. There are no tubercles in the neck. There are no accumulations in the abdomen. Form and qi are substantial. Spirit is robust. Zang-fu organs are harmonious and smooth. Pulse is peaceful. In such cases, variolation may be performed.
