Why can't I find Rushan's misty poetry novels?

Unknown, out of print, geographical restrictions, etc.

1, unknown: Rushan Fog is a relatively unpopular novel, which has not been widely spread and publicized like some famous works, and it is less likely to appear in search results.

2. Out of print: Rushan Mist is out of print. The book has stopped printing and selling, and it is difficult to find it in bookstores or on the Internet.

3. Geographical restrictions: Mist in Rushan is not distributed or sold in its area, which makes it impossible to find the book in the search results. The reason is that the copyright of the book is restricted by the region, or the book is only sold in a specific region.
