This is a book on the theory of Taijiquan by Teacher Wang Shujin. The demonstration photos feature Wang Fulai, his successor. You can learn the true transmission. It has been stored at home. I think it's relatively clean, but please check the photos for the current condition. I don't smoke, and I don't have any pets. Instant purchase is OK. Please note that the person who purchases it immediately will be given priority, even if negotiations are in progress. If you have any concerns about the condition of the book, please leave a comment. *Please refrain from purchasing if you are overly concerned about the condition, as this is a used item. Only those who understand are kindly requested to purchase.*
