What preparations should I make to open a violin studio?

Just go to industrial and commercial registration. I haven't opened it before. It is estimated that just like opening a musical instrument store, the big money is mainly piano and facade money. If you are a producer, it doesn't matter. You don't have to be in the piano, you have to be able to choose. You need to find a piano repairman. You can't sell the piano. If there is a small defect, go back to the factory to repair it, so the customer will be dissatisfied. If you have any other questions, keep asking.
