China passport number enquiry

What's the problem? I don't understand. If you mean the passport number, then I'm sorry, you can't find it at all. However, the passport numbers in different places are the same system, that is, the numbers are continuous, and the numbers handled at the same time may also be continuous. If one person did it yesterday and another person did it today, their passport numbers would be much worse. (Passports are issued every day in China) If you are asking about the validity period of passports, it has nothing to do with the departure date and entry date. If you ask about the validity of the visa in your passport, it has nothing to do with your departure, because it says when it will take effect, but the entry date must come back before the date marked on the visa. There is also a visa that starts from the date of your departure (that is, the day you enter the corresponding country). If you are asking about the entry and exit stamp on your passport, you should have an exit stamp and an entry stamp, which should also be stamped when you enter or leave other countries.
