Qian Yi is a sage in pediatrics, and his representative is "the direct prescription of pediatric medical certificate", which initiated the dialectical system of five internal organs in pediatrics, and treated from five internal organs (a pair). Liu Yun, the representative of Southern Song Dynasty, was the most complete pediatric monograph in the world at that time (B mistake). In Yuan Dynasty, Zeng and his representatives, as a book "Living Young Heart", were the concentrated exposition of neonatology in early Chinese medicine, and used San and Bushen Dihuang Pills to treat fetal movement disorder (C mistake). In the Ming Dynasty, Wanquan first put forward the theory of children's physiology and pathology that "three are more than enough, and four are insufficient". The treatment focuses on protecting stomach qi, and his works are quite abundant (D wrong). As an iron mirror of pediatrics, Xia Yuzhu, a representative of the Qing Dynasty, thought that "there are things inside and things outside", treated umbilical wind with "thirteen lamps" and attached importance to the application of massage therapy (E mistake).
