Where does Shenyang have a wholesale lock core lock?

As far as I know, there is no special lock cylinder market in Chengdu, and there is no large wholesale market. I have never heard of it.

As far as I know, some building materials markets sell locks, and of course they also sell lock cores. In the market selling electric cars, there are some locks or other locks selling electric cars. Of course, maybe you want to buy a computer hard disk lock, but not necessarily. After all, there are too many varieties of this thing.
