The Public Security Bureau where your household registration is located can now apply for it. However, if you are not in a provincial capital city and cannot apply for a personal visa, you can only apply for a tourist visa. . . But you can go there with a group. . .
You can take a look at the Shenzhen Staff International Travel Service. Last time I went with a group with an L visa, but I only had two days of free travel, so I could go and play by myself. . . Much more convenient than other tour groups. .
