Your ethnic group is Tujia, so I suggest you use "Banai Family". Banai and Miao people are remembered by readers because of Nanpai Uncle's Notes on Grave Robbery. Therefore, your use of the word "Banai Family" can appropriately reflect your national characteristics.

as for the LOGO, I suggest that you can find an agency to register the trademark. The cost is not high, and we will find out for you whether this trademark can be registered or not, and whether it has already been registered.

I'm Zheng Yang from Huashang Power Trademark Registration Company, and I can solve this problem for you. To provide you with three trademarks LOGO, and at the same time to search whether the trademarks can be registered, to provide you with all-round services. If you need it, my phone number is 158, and I hope it can help you.
