There are only three weapons in the world: American, European and Soviet.
Both American and European departments pay attention to precision, high cost and difficult manufacturing.
China can't be copied if he wants to, and the samples are not easy to get.
Soviet weapons are different. The Soviet Union's 156 project helped China to establish an industrial system, and before the relationship broke down, it gave a lot of weapons and related technical information, which laid the foundation for China.
The equipment of the army is basically Soviet.
In order to be consistent, I will definitely continue to imitate.
