These screenshots show that on October 22, 2012, Sina Weibo was censoring "Luzhou people's anger," (泸州 民愤) and it had stopped censoring it by October 28.
Yinggehai
These screenshots were taken on October 25, and show that searches for "Yinggehai" (莺歌海 - in Hainan) on Sina Weibo and Tencent Weibo returned no results, just censorship notices.
Zhenhai
On October 29, 2012, the state-sponsored Global Times
reported:
Following a massive week-long protest by residents, a controversial petrochemical project in the eastern city of Ningbo, Zhejiang Province, was suspended Sunday [October 28]. The protest only ended yesterday evening after clashes broke out between crowds and police in front of the local government compound.
Plans for a multibillion-yuan expansion of an oil refinery and chemical plant, located in Ningbo's Zhenhai district, were temporarily halted pending further "scientific assessments," Ningbo officials announced yesterday evening, vowing that that no "paraxylene (PX) project would be allowed in this city."
These screenshots show that, at some time on October 28, Sina Weibo began censoring searches for "Zhen Hai" (镇 海 - note the space, Sina Weibo had been censoring "Zhenhai" for several days already) and Liu Qi (刘奇 - the mayor of Ningbo). By November 4 Sina had stopped this censorship.
