2. This concept was first used to study rice agriculture in Java. In colonial and post-colonial Java, agricultural production has remained unchanged for a long time, without development, but only repeated and simple reproduction. Can not improve the unit per capita output value.

3. Education involution. To put it simply, at the beginning, each child only studied for four hours a day, and everyone lived in peace. Later, some children studied for six hours a day and were admitted to Tsinghua. When the parents saw it, it was not bad, so the children began to study for six hours every day, which brought everyone back to the same starting line.

Children spend more and more time on study, and the pressure of study is increasing, but the return of education is not rising but falling. It's like a group of people sharing a cake. The more anxious I am, the more I can't get it, and the more anxious I am. In the end, many cakes were wasted in the competition. Obviously, everyone is working hard, but getting less and less cakes.
