Sanda is very mature, comprehensive in technology and practical. If you are self-taught, I recommend you to watch Xia Liwen Sanda Tutorial in Baidu video. Starting with the most basic things of Sanda, the lectures are very systematic from shallow to deep. Xia Liwen used to be a Sanda coach in the Chinese People's Armed Police Force. You can enter Sanda Tutorial in Baidu video, and the person in the picture is wearing red vest shorts. In addition, you can also watch Zou Guojun's "Sanda King" video tutorial as a reference supplement. Zou Guojun was the main force of the former China national team. He once coached in Beijing Wushu Institute and Beijing Sanda Team, and his level is beyond doubt.
