Company name: Beijing Tianzheng Security XXX Co., Ltd.?

I think Tianzheng Security means good. There's no need to think of another one. How about Beijing Tianzheng Intelligent Security Co., Ltd., if allowed? Or Beijing Tianzheng Star Security Co., Ltd., which means knowing many stars. I believe there will be no duplication between the two. If not, I will reconsider.

Or Beijing Tianchen Star Security Co., Ltd. ..
