If you retweet or post something that has sensitive information or is considered reactionary, Sina Weibo will delete it and deal with the poster, possibly banning them, which is what it means to be harmonized by Sina Weibo.

Harmony is an Internet term that comes from and is often used on the Chinese Internet. The term "river crab" is used by netizens to refer to the act of blocking and covering up negative news, and also means that the crab is "'rampant' (pun intended) and domineering". The word "aquatic" sometimes has the same meaning as "river crab".

In some Chinese forums, the word "harmony" itself has become a banned keyword. To get around this blocking, netizens substitute "river crab" or "harmony" harmonically.

A certain department, in response to the slogan of "Harmonious Society" and the harmony of the network, blocked many commonly used words on the Internet and daily communication terms, "push-ups" is a typical example, which caused a lot of inconvenience to the majority of netizens on the communication. So the end of 08 derived from the "beast" and other valuable species. The river crab is also one of them.

The river crab is a harmonic of harmony, and is often used by netizens to refer to "harmony" in the network. The famous beast said.

We want harmony, we want love
