I'm going to work hard and write a long, long story.
Setting: People are wandering in the rivers and lakes. How can they not be knifed? Silently, the knife was hit on his head. All along, everyone thought he was sick. When he was happy, he went to the operating room to get a knife. When he was unhappy, he went to the operating room to get a knife = =.
The knife of the Yellow River touches my heart. To put it mildly, what cannot be passed is called memory.
What's in it, practice it, just do it when it's time to do it. . .
