I am a citizen of one of the countries (France) eligible for a 144-hour visa-free transit in some areas of Mainland China. I understand that to be granted the visa-free entry, I must have an onward ticket to a destination that is different from where I came from when entering Mainland China.
Am I allowed to leave Mainland China in a different way than this onward ticket, assuming I'm still leaving within 144 hours (starting from 00:01 on the day following the day of entry). If so, must I notify anyone prior to leaving Mainland China?
