The teahouse method is the best. A relatively quiet environment and a hall are the layout of a tea house. Remember to be simple and unsophisticated. Don’t follow the route of a clubhouse or a salon, which are foreigners’ things. What you are doing is a Chinese business. Chinese people like their own things deep down. .
Then there are several side halls. Categorize all the ideas you have in mind. Each hall has a theme and each hall has a key point. You can make your own choice. Also, if you make it into a teahouse, don’t ask for oil paintings. I’m serious, it’s very uncoordinated.
I don’t know what your plan looks like, so I don’t know what kind of suggestions I can give you. However, there is one thing you must remember, the theme. After you determine the theme, all your actions will be done around this theme. Don't do too many things that you don't want to do, otherwise it will easily become different.
Chinese paintings, antiques, jade, purple sand, porcelain, calligraphy, and jade are all favored by Chinese people. Imagine that you hang a landscape of fish and insects here, and get an oil painting there. Does it feel reliable?
To be honest, I had a similar idea, but it was after I turned 60. Haha, I really don’t have the funds now.
I wish you success, my friend, this is a good opportunity to accumulate contacts. If you are not short of money, then I will definitely support you in doing this. If you don't have a stable source of funds, I suggest you consider other things. This is a very expensive job. If you do it well, you will make a lot of money. If you don't do it well, you will jump off the building.
