Zhu Tian Cai commented that small frame tradition routines also used to be practiced by "retired" Chen villagers. The Xiaojia forms can be practiced with less of the demanding leaping, stomping, low stances, and intensive fajing of the advanced Big Frame tradition routines. Form movements emphasized use of the more subtle internal skills, which was a more appropriate regimen for the bodies of elderly practitioners. He also observed that young children used to imitate Small Frame routines by watching older villagers practicing, and this was encouraged for health reasons.
