I plan to enter Mainland China with the transit-without-visa (TWOV) program.
I fly from country X to China, then fly from China to country Y. Is there any minimum stay required in country Y when applying for a visa-free transit entry in China?
E.g., if I fly country X -> China for 144 hours -> country Y for 2 hours -> country X, is that still fine to get the visa-free entry in China? I'm asking as I wonder whether the Chinese immigration officials would think that in that case country Y is the transit place and the state in China is the purpose of the trip, and if so, whether that would represent a reason to deny entry to China.
