Who knows the story of learning carpentry in ancient times? Please tell me.

After liberation, my father taught himself carpentry and became a means of making a living. When I was young, I was strong, so I sawed boards for the shipping company. When you get older, you start selling furniture in the seller's house. In the era of capitalist tail-cutting, people earn work points by working in the production team during the day and make furniture at home at night. After making a batch, they took their sister with them in the middle of the night, carrying tables, chairs and benches, walked twenty or thirty kilometers of mountain roads and went back to the county to sell them. Ironically, the county government bought a desk from my father while the country was cutting its tail. When I was a child, my father often told me that I made more than half of the county government desks.
