I think palace dramas are also a bit like being easy to get approved, so they have become popular. However, I couldn’t find any relevant evidence, but ancient costume dramas were indeed occupied by palace dramas before, while historical dramas became less and less. This is indeed directly related to censorship, because as long as it is a historical drama, it can use the past to satirize the present.
In order to avoid censorship, the original Danmei novels (homosexual love novels, mainly BL (Boys Love)) based on love were modified into brotherhood. This is a Dangai drama, but even so, it was still restricted.
Internet movies mainly refer to movies that are first released on streaming media platforms. Because they did not need to be filed at the beginning, the scale is larger than that of theater movies that need to be filed. Therefore, after the anti-Japanese drama was restricted, more bizarre Cult films/B movies were transferred to Internet movies… (but this does not mean that Internet movies are all Cult films/B movies)
