1930. The description of Yilu in Chen style parlance are: Movements are large and stretching, Footwork is brisk and steady, the body is naturally straight, the entire body controlled by internal energy. (拳架舒展大方，步法轻灵稳健，身法中正自然，内劲统领全身。) The exercise requires the close coordination between mind-intent, internal energy, and the body; the outer appearance is an arc and the internal energy travels along the path of a spiral; the energy winds around so that the external action appears soft but corresponding internal action is hard. (练习时，要求意、气、身密切配合，外形走弧线，内劲走螺旋，缠绕圆转，外柔内刚。) In Chenjiagou, the Laojia is considered the foundation form. Because it is steady, fluid, and readily comprehended, it is always taught first. Large Frame: New frame (Xinjia) tradition After Chen Zhaopei's death, taijiquan practitioners in Chen Village petitioned Chen Zhaokui (陈照奎, 1928 – 1981), Chen Fake's only living son, to come and continue their education in the art. When Chen Zhaokui visited Chen Village to assist and later succeed Chen Zhaopei in training a new generation of practitioners, (e.g. the "Four Jingang," aka the "Four Tigers": Chen Xiaowang (陈小旺), Chen Zhenglei (陈正雷), Wang Xi'an (王西安), and Zhu Tiancai (朱天才)), he taught Chen Fake's practice methods that were unfamiliar to them. He made three separate visits, totalling under two years. Zhu Tian Cai, who was a young man at the time, claimed that they all started calling it "Xinjia" (New Frame) because it seemed adapted from the teachings they had previously learned from Chen Zhaopei, which they called “Laojia” (Old Frame). Now, it is officially called Xinjia (新架, New Frame) which represents what Chen Zhaopei's students were able to learn from Chen Zhaokui's three separate visits. In Xinjia, there are 83 moves in the First Form and 71 moves in Second Form. Chen Xiaoxing, Chen Xiaowang’s brother and a student of Chen Zhaokui, said the primary differences between the Xinjia and Laojia are the small circles, which highlight the turning of the wrists and make visible the folding of the chest and waist. Xiongyao zhedie (chest and waist layered folding) is the coordinated opening and closing of back and chest along with a type of rippling wave (folding) running vertically up and down the dantian/waist area, connected to twisting of the waist/torso. Rotations of the waist and dantian become more apparent in Xinjia. It was also recounted that by the time of the Cultural Revolution, Chen Village was losing qualified teachers of Taijiquan, and the resident students, who are now
