From a medical point of view, it should be when blood gas is weak (to ensure normal physiological needs), and it is relatively better to practice Tai Ji Chuan.

This is because: Tai Ji Chuan is also a sport. We will consume a lot of energy when practicing, so it is better when the blood gas is weak, but we must ensure normal physiological needs. Tai Chi emphasizes calmness and slowness, and is one of the best ways to keep fit. Therefore, I think it is best to practice in the morning in a day. It adds interest and spirit to the life of the day and makes us feel positive.
