What do boys mean when they say that girls are Hei Hu?

Scare people. This is Shaanxi dialect, which means to scare people, that is, "Hei Hu" in spoken language. Shaanxi dialect can be roughly divided into three areas: Zhongyuan Mandarin, Jin Mandarin and Southwest Mandarin. What we usually call "Shaanxi dialect" only refers to Guanzhong dialect.

Usually used to describe a person who is not mature enough. To put it mildly, we should be dignified and strong, and stay a little dull. To put it bluntly, it's just a bit silly. I don't think about things. This tiger is a northeast dialect, strictly speaking, it is called "northeastern mandarin".
