"Huancheng Deep" has been published by Anhui Literature and Art Publishing House, and has been renamed "Snow in the City". It can be ordered from all major online bookstores (such as Boku Bookstore, Weilan Bookstore, Xinhua Bookstore, Joyo. Com, Dangdang. Com, etc.).
Sorry, the picture on the cover is beyond my ability. Anyway, it doesn't look like the character in my eyes.
This article is the prototype of "Huancheng Deep", and is given to friends who follow the article. "Huan She" is what I am currently writing with great efforts. I work slowly and carefully, with a rigorous attitude and elegant writing (I will praise it first). "He Chen" retains many plots from the original creation.
