Self-study technology is quite good. You can improve your skills or something, and you can pass it on to your descendants. The cost of opening a shop by yourself is much less, and all links are controlled by yourself. It is said that there is a very good "Potter's rattan pepper" in Chengdu. The store decoration style is uncomfortable, and the signboard image is very beautiful. It is also mentioned that the store provides technical training. You can go to their shop to learn technology and management. I think it should be easy to open my own shop after learning.
