Zhōu Dàiyú 周带鱼
Nickname for nationalistic and anti-American writer Zhou Xiaoping. Zhou, who is loose with facts and quick to slander, has won the praise of President Xi Jinping for his "positive energy."
Zhou Xiaoping earned his nickname during the crackdown on Big Vs in 2013. In an August 26 blog post, Zhou excoriated Charles Xue, the Weibo celebrity and Chinese-American businessman who was detained for "soliciting prostitutes," only to appear on CCTV days later apologizing for his online behavior:
To promote sales of water purifiers, Xue Manzi [Charles Xue] claims China's water is poisoned. Because of this, Zhoushan's cutlassfish farms cannot sell anything, leaving countless fish farming households to face bankruptcy. Xue is guilty of a most terrible crime. Who will punish him?
Cutlassfish, it turns out, cannot be farmed, and netizens will not let Zhou forget it.
Example of "Cutlassfish Zhou":
Wenmanglishiwei (@文盲李世威): Because he refuted Cutlassfish Zhou point-by-point, Fang Zhouzi's Sina blog has been preemptively shut down. Soon we may not be able to see his Weibo or WeChat, either... (October 22, 2014)
