Is the Hell Department in The Journey to the West a part of Taoism or Buddhism?

First of all, you need to find out whether hell or hell is a foreign concept (that is, whether it was brought in by Buddhism).

I once asked a friend of orthodox school, and he told me that there is no such thing as reincarnation or even afterlife in their teachings. On the Zhihu, I have seen many monks say so. But at the same time, I also saw some Taoists say that Taoists are talking about the past and the future.

So it's hard to say whether Buddhism introduced this concept, or Taoism introduced this concept, which further influenced Buddhism introduced into China, or whether the two sides merged in China.

If it is based on the Journey to the West, the hell should be controlled by Taoism, but Buddhism can influence it and is not controlled by it.

All reincarnations are through the underworld. In the dispute between Buddhism and Taoism, it can be said that it is a neutral camp. The Tao is a judge with a face, and the Buddha is a king with soil. However, some Buddhist scriptures also say that the Ten Halls of Hades belong to Buddhist sects, which is different.
