China is the last major economy still attempting to stamp out the domestic spread of Covid-19, and has continued to shut down entire cities, seal off neighbourhoods and impose mandatory tests on millions.Driven by the fast-spreading Omicron variant, daily cases in the country hit 29,157 on Wednesday -- low compared to most other countries but nearing the domestic record set earlier this year."Some people are watching World Cup matches in person with no masks, some have been locked at home for a month, locked on campus for two months without even being able to step out the door," a Guangdong-based user on the Twitter-like Weibo platform wrote on Wednesday.An open letter questioning the country's Covid-19 policies and asking if China was "on the same planet" as Qatar spread on the popular WeChat messaging app on Tuesday, before censors removed it from the platform.Public anger over the seemingly arbitrary restrictions and sudden disruptions has recently erupted in rare protests, including in southern China's Guangzhou this month where hundreds of residents took to the streets in defiance of a compulsory lockdown."
