I was going to do a big job today, but I was notified that I would do a high-frequency experiment for a day today.

Today may be an afternoon update.,It may also be the evening.,I hope you understand.,I've had something happen recently.,Originally, I was preparing three chapters a day for tomorrow's manuscript.,But recently it just used up.。

Excuse me.

In addition, it is free in December, and I try to write as much as I can, waiting for everyone to come to 17K to report.
