What do you mean when people say you are stupid?

It means silly and belongs to a kind of ridicule. At this time, you need to recognize each other's tone. If it's a taunt from a good friend, just laugh it off.

If you are an unfamiliar friend, you should ask the other person why he said so, and you can't eat dumb.

Teasing is a Chinese word, pronounced as tiáo k?n or Dià o K NR, which means verbal teasing and ridicule. I mean kidding. From "A Flower, Send Che Wenqing to Seclusion" and "Flower Moon Mark".
