It is a family-run small shop of several square meters. This is a very poor family. Dealing with them feels like communicating with people who haven't graduated from primary school. What I do has quality problems, poor materials and poor construction. It's too bad to ask them to rework and pass the buck. I don't know where they bought the goods. I think it is bad luck. His mother is also an unreasonable person. The door-to-door theory is useless. It's the feeling of being a hooligan who can't fight anymore. I hope I can close the store as soon as possible and do whatever I want. It won't hurt anyone.
