How does China go to work abroad?

Different countries have different procedures for going abroad. There are two main types: passport and visa. What are they? For example, didn't Tang Priest always hold customs clearance documents when he went to the Western Heaven to learn Buddhist scriptures? It is actually similar to a passport, just like an ID card, to prove its identity to foreigners. The seal of the king of another country that Tang Priest wants is similar to a visa. It is a symbol of the sovereignty of other countries. The Tang Priest went through the customs, and the frontier defense won't stop him, which is also a record of visiting the local area. Of course, this kind of visa also includes passes, landing visa and other types, and even visa-free. But no matter which country you are going to, you must apply for a passport first.
