Chen Xiaoxing also emphasized that "the fundamental principles of the two frames, (Laojia and Xinjia), are the same with regards to postural requirements and movement principles. Both require the practitioner to exhibit movements that are continuous, round and pliant, connecting all movements section by section and closely synchronising the actions of the upper and lower body...The Old and New Frames should not be viewed as different entities because both are foundation forms. If you look beyond the superficial differences, the Old Frame and New Frame are the same style, sharing the same origin and guiding principles. In Chenjiagou, people have the advantage of knowing both the first routines." However, because of common fundamentals and training methods, either frame, Laojia or Xinjia, can be trained as a complete curriculum.
