You need a visa to go to Kinmen. One is the Taiwan Travel Permit for Mainland Residents and the other is the Taiwan Entry Permit of the Republic of China. Both of them require valid visas.

Visas play an important role in a country's control of entry and exit personnel, protection of homeland security, and prevention of illegal immigrants and criminals.

A passport is proof of the holder's nationality and identity, while a visa is a permit from a sovereign country to allow foreign citizens or its own citizens to enter or exit the country or pass through the country's borders.

Visas are generally endorsed on the passport, and some are endorsed on other travel documents that replace the passport. Some also issue separate visas.

For example, the immigration visa of the United States and Canada is a piece of A4-sized paper, and Singapore also issues a separate visa to foreigners. Generally speaking, the visa must be used at the same time as the passport to be valid.

Extended information: For foreigners, different entry visas are generally issued based on the applicant's identity and purpose of entry, such as tourist, family visit, immigration, study abroad, work, etc. visas, and the residence time after entry is limited.

Depending on the type of visa, the relevant documents required are also different.

Generally, there are fewer restrictions on applications for short-term residence, and the waiting time for approval is also shorter.

For long-term residence, applications are more restrictive and the waiting time for approval is also longer.

A country has no obligation to allow foreigners to enter the country unconditionally (unless there is a treaty), and a foreigner does not have the right to ask the government of a country to allow him to enter.

A sovereign country always imposes conditional restrictions on the entry of foreigners.

With the development of international trade, international political relations, and the prosperity of tourism, visa regulations in many countries tend to be simplified.

There are also agreements between countries to exempt each other from visas or simplify visa procedures.
