I want to represent smart locks and fingerprint locks to find manufacturers there, ok?

There are many brands of smart locks. If you are an agent in a first-tier city, you should recommend a first-tier brand because you have the spending power. If you are in a second-and third-tier city, you still need to know which brands are available at present, or choose a better brand. In addition, the profit of doing business is also a key consideration. We must carefully verify the strength and reputation of this brand before cooperation. Finally, we need to look at the functional stability of the smart lock, and don't deliberately pursue the price.
