How many days can a Romanian passport stay in China?

Passport is a necessary document for anyone to travel from one country to another, which is used to prove the identity of the holder. Passport alone cannot determine whether the holder is allowed to stay abroad, let alone the length of stay.

The visa issued by the destination country determines whether a person is allowed to leave the country, whether he is allowed to enter the country, and the duration of his stay. The length of stay allowed depends on the purpose of the person's visit, from one day (such as transit) to permanent (such as immigration). Some are only allowed to be used once, such as transit and one-time travel. It is invalid if it is stamped with the entry and exit stamp. Others allow multiple uses, such as business, study, immigration (and many round-trip tours recently started in some countries) and so on.

An exception is that if there is a bilateral agreement between two countries (such as China and Sri Lanka) that allows visa exemption, visa requirements can be waived for departure and entry, and only valid air tickets and hotel reservations can be provided for confirmation. This method is actually a special visa, a package visa for all nationals of another country under an agreement, not a "visa-free".
