Is the modification of furniture a patent for utility model?

As a utility model patent, you can play with it. With a patent certificate, you can brag to your friends, but this has no commercial value at all. The protection of patents in China is very weak, and the laws are not perfect. Many furniture factories in Chongqing don't even have licenses, but only a rented factory and a few migrant workers, but they all produce international brand furniture such as Henry Dai and dreamer. So, if you want to make money from this, don't.
