A rough translation of the Chinese text above:
Most of the taiji push hands videos people see are about strong, big and experienced masters pushing with small, weak and inexperienced students. More so is the Master pushing with the same few students for years without working with anyone else. It is a rare sight to see people like Chen Xu in this video, small and normal dealing with opponents larger than him by using taiji manipulative skills, traveling the world to touch hands with anyone he comes into contact with, most of them at master’s level and sometimes, with professionals. Without knowing basic background information such as the above, the viewer can gain little insight into what they are doing. This is a matter of Kungfu, but more so it is a matter of attitude towards taiji.
