Sensitive Words: Chen Guangcheng and More
Other: US + petition office, Gary Locke + petition office (Netizens have taken to calling the US embassy China’s “Supreme Petition Office” and Gary Locke its “director.” More from CDT Chinese.)
Related to the Anniversary of Tiananmen: May Fourth + one month (Youth Day is exactly one month before June 4, the day the Tiananmen Massacre began), nine eight, eight nine (the latter two using the characters for writing numbers on checks)
Note: All Chinese-language words are tested using simplified characters. The same terms in traditional characters occasionally return different results.
CDT Chinese runs a project that crowd-sources filtered keywords on Sina Weibo search. CDT independently tests the keywords before posting them, but some searches later become accessible again. We welcome readers to contribute to this project so that we can include the most up-to-date information.
