I asked him to do it at first. At that time, there was no erp construction management system, and the construction process was face-to-face communication with the supervisor. Now it's much more convenient to have a mobile phone, because I was satisfied with what I did at the earliest, and a friend behind me has decoration needs. I went to know about it again. A small team was set up during the construction to keep track of the renovation progress at all times, which saved me trouble. There are many young designers in this company, but people are more patient and responsible. The designer who first contacted me is still here. I heard that he did a good job, and now he is the manager of the design department. Generally speaking, if it is decoration, it is more cost-effective to find their whole package, but it is not so cost-effective if it is half package.
