I want to go to Xinmatai for a self-help tour. How to get a visa? Do I need visas from three countries?

As long as you go abroad, you need to apply for a visa unless it is a visa-free country. Singapore, Malaysia and Thailand are not visa-free countries, so you need to apply for a visa to travel in these three countries.

Visa refers to the procedure of endorsement and seal of passports or other travel documents held by domestic or foreign citizens by the sovereign organs of a country to show that they are allowed to enter, exit or transit. It can also be said that it is an endorsement certificate issued to them. Generally speaking, a visa is a document issued by a country's entry-exit administration (such as immigration bureau or its embassy or consulate abroad) to approve the entry of foreign citizens.

Passport is the holder's nationality and identity certificate, and visa is the permission certificate of a sovereign country to allow foreign citizens or their own citizens to enter, exit or transit.
