Taiwan transit ban on PRC citizens (ex-China)
(This should be in the Taiwan transit thread, but since the topic was brought up here...)
At least for Chinese citizens living in China, it's not hard to get a 大通證. The hard thing to get is the Entry-exit permit (入台證), the permit to enter Taiwan, issued by Taiwan. Right now Taiwan is only allowing certain categories of travelers (including Chinese citizens residing outside of China). Once you have the document issued by Taiwan, you just go to an entry-exit bureau run by the PSB and get the 大通證 + endorsement. If one is not flying to Taiwan directly from China, then no 大通證 is required. But as I mentioned in the other thread, Chinese citizens may get a lecture from immigration if they fly from Taiwan to China using only their PRC passport.
