I will Bury the Gods:

Headaches caused by lack of sleep are not Yang.

I'm sorry, I've stretched my legs again. I've been sleeping for three or four hours these days before waking up. I don't feel sleepy, but I have a severe headache. It's been like this for several days. The update is basically written... Today I want to take a rest tonight, try to get a good night's sleep, and refresh myself.

Because it is my own physical problem, it is not fair to ask for leave today, and the update tonight will be made up tomorrow.

Apologies to those who are still waiting for updates.
