fènqīng 粪青angry youth” (愤青 fènqīng), young people who are extremely vocal with their nationalism. “Angry youth” are known to whip up anti-Japanese and anti-Western fervor: they founded the website Anti-CNN in response to CNN’s coverage of the 2008 Tibet riots, and frequently catalyze anti-Japanese street protests. “Angry youth” cause the Chinese government considerable anxiety, as they may organize and resist the control of the authorities. The derogatory “shit youth” implies that their fervor is irrational and even dangerous.
On Weibo, one user elucidates the difference between shit youth and other young people:
Maizangluopo (@埋葬落魄): Those who dismiss everything, cry and curse, are shit youths. Those who are discontent with reality, eager to create change, and cry out in anger are angry youths. Only those who move forward step by step are striving youths. Too many people carry the banner of thought and personality in the name of the angry youth, yet act in the manner of shit youths. Let’s use our youth to accomplish something concrete; if we do not strive, what right do we have to “rage?!”
