Taiji is not what you see!
Wu Shaozhi of Linyi and Chen Xu of Zibo came to visit. They stayed for two days. Watched Wu's form, made corrections and comments. He made progress again. Chen Xu came to Daqingshan through the Zibo Taijiquan Competition held in Yiyuan that the Daqingshan team attended. His push hands was quite good. He noticed that the feeling of push hands is not what he expected from observing my students at the competition.
