Learning still has to be repeated (a "stupid bird" like me should not only fly first, but also return successfully!)

During the summer vacation, I found that I was a little ashamed of the sentence on the home page:

@H_ 403_ 44 @ Gou Youheng, why sleep at night and wake up at night. The most unhelpful thing is to expose the cold for ten days in one day!

I feel that I can't move when I learn, and I also feel tired.

However, if you go on like this, you must dig a hole for yourself. You still have to work hard and continue to learn the journey. Also, if anyone sees my note and moves forward like me, send a word here to encourage each other!
