What's the longest covid-19 quarantine?

I read on https://www.cnn.com/2021/12/10/business/hong-kong-covid-quarantine-pilots-intl-hnk/index.html that Hong Kong has a 4-week quarantine (including at-home self isolation)

This typically means that pilots fly out for several weeks, cannot leave their hotel rooms upon arriving at their destination, and return to hotel quarantine in Hong Kong for another two weeks, according to the Cathay pilots who spoke to CNN Business. That is then followed by a further two weeks of isolation at home, they said.

What's the longest covid-19 quarantine in the world? Is that this 4-week quarantine, or does there exist longer quarantine? I'm interested in both cases when self-isolation is included or excluded from the quarantine time. I'm interested in all quarantine policies (past and current) during the pandemic.
