river crab 河蟹

river crab
繁：河蟹
简：河蟹

而”河蟹“又與中國官方一再強調的構建和諧社會的”和諧”同音。

Bloggers started to refer to being censored as having been “harmonised” – bei hexie le 被和谐了 – but, by changing the tones in Chinese or changing the characters, you can fudge the meaning. So another hexie is river crab 河蟹。In other words, when you see an image of a river crab on the internet in China, it is likely to be a reference to something having been censored.
