Muay Thai, the fight is fierce, but it does great damage to your knees, elbows and other joints. If you want to be healthy after middle age, it is recommended not to learn this.

I suggest learning Sanda or Jeet Kune Do. The development trend of modern Sanda is: boxing with fists, taekwondo with legs and wrestling with wrestling. In fact, you have also learned several techniques when you study Sanda. Jeet Kune Do has more lock-body grasping methods than Sanda. However, there are fewer classes to teach this. Taekwondo is suitable for self-cultivation, but fighting is not necessarily practical. Because it pays too much attention to leg skills, it is ignored in boxing.

There are classes to teach Sanda in Guangzhou. Search on Baidu website. Guangzhou Sanda is it. There are many.
