Corpse in Coal Cave Dwelling

In Heishui Village, on a desolate stone road, a lonely coal cave entrance faces the cold east wind. The narrow opening looked like a cold mouth that could never be opened. The entrance to the abandoned black coal cave was blocked and then dug open. Who was the body inside? Who is the murderer? Is it good or evil? And people are just like their characters, with each stroke and pull, forming the good and evil of life. The ups and downs reflect the entanglement between the appearance and the heart.
