According to the *Shenghui Fang* (Sanitary Handbook): In children with deficient muscles, wind-toxic heat pathogens invade. When heat-toxin clashes with blood and qi, the skin becomes red and swollen. This wind follows the movement of qi, wandering without a fixed location, hence the name "Youzhong" (Wandering Swelling). It is also stated: The manifestation of Youzhong involves colors of green, yellow, red, and white, lacking a fixed hue, wandering within the skin, with a slight luster on the flesh; this is Youzhong.
