What is the quality of Youlibang putty?

In Wuhan, the brand "Youlibang" is quite famous. I have been running decoration materials for some time, and the contractor recommended to buy the putty powder of Youlibang, saying that the whiteness and hardness are very good. I don't quite understand it anyway. When I went to the building materials market, I saw this brand of putty powder everywhere. By comparison, although it is a little expensive, the decoration should be cautious. . . The more basic the material, the better you should choose. . . . . As for Nippon paint, I have only heard of it, and there is one in Duobang.
