"Lao Wang came to Anhui with his family from his sister who lived in Shanxi at the age of 61. Lao Wang had to move to a cave in the mountain with his wife due to the poor conditions at home
This is a long abandoned cave, far from the local village, and there is no water supply, because the water shortage caused the whole family to basically not clean themselves, even brushing their teeth and washing their face is a luxury.
The only income he earns is only a little bit of money from Lao Wang's odd jobs. He and his wife gave birth to four children, two children and two daughters, and their lives were very difficult.
