Excuse me, which fairy knows about smuggling guns and ammunition? Are customs security checks all furnishings?

First of all, buddies should understand that smuggling ≠ overseas imports, as long as things that are "not circulated through formal channels" are circulated to the market, are smuggled goods.

Guns and ammunition are not allowed to be sold in the market in China, but it does not mean that they are not produced in China. On the contrary, China, as one of the five permanent members of the United Nations, has the right to buy and sell arms internationally, which is one of the reasons why the P5 are dubbed the five hooligans. In principle, arms trading by other countries is against international law.

Since so much has been produced, even a little has escaped from the factory by tens of millions ... This should be said to be common sense (but it is ridiculous to see someone questioning the custom).
