Is Tianjin a free city in Taiwan Province Province?

Tianjin was a free and open city in Taiwan Province Province a long time ago. Free travel in Taiwan Province Province requires a Taiwan Pass. He has to sign a visa separately and a group visa. Only by traveling freely and opening the city can you sign a group visa. Group visa is to apply for a pass from a travel agency after registration. I suggest you join a group tour, and the public letter tour is also quite good. However, you must apply for a pass yourself, and then ask the travel agency to apply for an entry permit. So, in addition to the pass, you also need an entry permit. After that, you can make a route around the island of Taiwan Province Province. Taiwan Province Province is too cold and too hot in July, August and January. Other times are still very suitable for travel. Especially in autumn, which is the best season for sunny and cool weather. Or there is a music festival in March and April, which is also very distinctive.
