To be honest, I have never heard of them before and I don’t particularly trust them. I always thought about what to do if I was cheated. I checked the official website and checked various platforms of Tianyan Industry and Commerce, and found the registration information office. I still didn’t trust the address or anything like that, but the company was in urgent need of the patent, so we made the transaction with trepidation. It can be said that it was really a gamble at the time, maybe because I was more cautious in doing things, until the transaction was finally completed and the patent was obtained. , I finally feel at ease, the number must be hundreds of thousands, not a small number!
