First of all, in the feudal history of China in 2000, China's productivity and thought did not stagnate, but developed in a spiral, except that there was no brilliant outbreak in the pre-Qin period and no great leap forward in science, technology and thought in the modern west.

After the Qin Dynasty, China has been under centralized rule. In order to maintain their rule, rulers need to imprison their thoughts, only cultivate obedient people, and do not need all kinds of heretical thoughts, which limits the development of their thoughts.

The development of China's productive forces has been good, and various factors of productive forces have been improving, but it will be interrupted as soon as the war is over, and prosperity will be restored immediately after the war. Since modern times, the great development of scientific and technological productive forces has taken place in the west, which is a leap far beyond other ethnic groups in other regions, so the development of productive forces in China is lagging behind.

Generally speaking, the development of feudal productive forces in China in 2000 was good, slightly better than other ethnic groups in other regions, and the ideological development was poor. Western modern times is a leap, so it seems that other regions and ethnic groups are backward.
