How to write group messages when ktv opens the door?

The premise is to send it to customers to let them know that you sent a business opening message, not a harassing message. You can do this: If you are an old customer, you should say: Thank you for your patronage many times. When shall we open the new store? I hope everyone will support me a lot. Your support is our motivation. If you are a new customer, you should say: What is this shop? After careful preparation, when will the new branch be opened? I hope you can visit us more. With your support, our store will get better and better.
