I remember my grandfather belongs to the spirit of the old cow. Although people are gone, his simple spirit has been passed down in his hometown. Actually, it's no big deal. It was a commune in a certain period and had its own land. During this period, my grandfather was also relatively simple.
At that time, everyone dried sweet potatoes, usually cut them directly and put them on the ground, and then dried all the food and put them away. At that time, dried sweet potatoes were all dried on the ground, and one night there was a strong wind. At that time, my grandfather was worried that the dried sweet potatoes would be blown away, and he didn't sleep a wink at night, fearing that the dried sweet potatoes would be blown away. Then I didn't know, so I ran to the ground and came back to tell my mother that the dried sweet potatoes were okay. At that time, my mother asked him if our sweet potato was okay. I don't know our dried sweet potatoes. I went to the commune field and looked at the dried sweet potatoes. Not bad. My mother was angry at that time. She didn't look at her own, she looked at the commune first, so people at that time were relatively practical and had the spirit of an old ox.
But now, after all, the society has progressed, and the persistent spirit of the old ox should be advocated, but the practice of the old ox cannot be advocated. After all, all walks of life now don't need your efforts, but your brains. Only by using your head can you do a good job. Therefore, the spirit of the old ox has a market, and his practice has no market.
Nowadays, everything needs brains to produce, and relying on patents means relying on your own wisdom, so you need to master things flexibly, and technology is the primary productive force.
