Do I need a visa for a one-day trip from Xiamen to Kinmen?

A one-day trip from Xiamen to Kinmen requires a visa. According to Article 9 of the Exit and Entry Administration Law, citizens of China should apply for passports or other travel documents when leaving the country, and citizens of China need to apply for visas or other entry permits when going to other countries or regions. However, unless the China government has signed visa-free agreements with other governments or the Ministry of Public Security and the Ministry of Foreign Affairs have otherwise provided, Article 10 shows that citizens of China who travel between the Mainland and the Hong Kong Special Administrative Region and the Macao Special Administrative Region, and citizens of China who travel between the Mainland and Taiwan Province Province, shall apply for a pass according to law and abide by the relevant provisions of this Law, and the specific administrative measures shall be formulated by the State Council. The procedures for a one-day trip from Xiamen to Kinmen are to apply for a mainland resident's pass to and from Taiwan and a tourist G-sign, and then apply for an entry permit with a mainland resident's pass to and from Taiwan. Only by holding mainland residents' passes and entry permits to Taiwan can they officially travel to Taiwan.
