Where is the best place for painting and mounting in Beijing?

I am a painter who belongs to the Beipiao family and have been working in Beijing for more than 20 years. For a painter like me, Rong Baozhai would not dare or want to go in and frame paintings. I can’t remember exactly how many framers I have dealt with until now. When I came to Beijing, there was a hand-made framer named Li who left a deep impression on me. He was a good person, a down-to-earth person, and didn’t talk much. But when I went to frame it again At the time of the painting, they had moved and have not been in touch with each other until now. I heard from friends around them that they had made some money by mounting paintings. They were getting older and their backs couldn't bear it, so they returned to their hometown. Later, I went to several places where I had to hand-paint paintings, but they were all unsatisfactory. Either the quality was not good, or my character was not very good, and the place was too dirty and messy. There was not even a place to put my feet. It was smoky... In the past few years I also know a hand-mounted painter like Master Li. He is good at mounting paintings, he doesn’t talk much, and he has a professional eye for art. The mounting workshop is clean, spacious and bright, and we can sit and drink tea and chat together. , we are friends now.
