Do I need to be quarantined when I return to Shanghai from Jiashan on the 31st?

Based on my current experience of traveling between Shanghai and Jiangsu, I can only tell you that it is not necessary yet, because Jiashan is still a low-risk area. Currently, entering Shanghai only requires a health certificate and temperature measurement, and no nucleic acid test is provided. Reporting requirements will not require quarantine. But now the epidemic is like a mole in the game of whack-a-mole, popping up everywhere. It is difficult to say that Jiashan will definitely be fine by the 31st. We can only hope that Jiashan is safe and there will be no problems by then. Because according to current regulations, people from high-risk areas are generally not allowed to enter Shanghai.
