Does the Taijiquan exercise book sold in the market conform to the tradition? Is there anything to pay attention to when practicing?

Much the same, but after learning a set of routines, you must read theoretical books. Only under the guidance of correct theories can you have better results. That is, what professionals call "positive boxing", without correct boxing, the effect is not great. Good theoretical books are hard to see in the market. A good theoretical book must be written by the authentic sect of Taiji Chuan, so you must choose carefully and buy carefully.
