Childhood-sleep protects yang.

Midnight 1 1 till morning 1 It's called Zishi. This time is the negative pole of Tai Chi life clock in a day. According to the law of the growth and decline of Yin and Yang, Yin is the heaviest at this time, and Yin dominates sleep, so we must follow this law of the growth and decline of Yin and Yang, and we will be in a state of deep sleep at this time. Attention, everyone, it is not this time to sleep, but this time should have been in a deep sleep state. So when should I go to bed? It should be around 10. When I was a child, I was on duty. When bravery is born in the sun, it happens that the yang has just grown out and it is still very weak. We need to protect this Yang in particular. How should we protect it? Sleep is best for protection, so stop dancing, singing and sleeping in the middle of the night. Yang will be raised at this time, and it should be protected from its young age.
