A: If you are under the 144-hour visa-free transit, you are required to stay within the administrative areas of the Shanghai Municipality, Jiangsu and Zhejiang provinces, and depart within the permitted duration.

In case you have to stay beyond 144 hours or outside of the permitted areas due to special circumstances, you must apply for a stay permit with the exit-entry department of the public security bureau at the provincial or city level.
