Well countries surrounding China should be happy they are adopting the zero tolerance because if not, covid of any variant could spread once again. The Chinese are confident that way though, they are more cooperative to their government than trying to impress their neighbors that they can fight back the police or so. It may look like concentration camp but its for the best. People just have to follow what authorities are doing for it to be over.
Countries surrounding China will be happy for the Chinese government adopting zero-tolerance cause no one wants the previous spread of the virus that happened in Wuhan to repeat again but there's always a way to do something which all the country's citizens will obey the government order rather than locking people inside their homes and forcing them to take a daily test.
