I got a network cable in Shenzhen. I thought it was Tietong. I didn't know what it was until later, doctor. The network cable made by the network communication company itself. I used one.

You can tell by this name that it is a private company. Tietong is not good either, and it is also deceptive. The year before last, he paid more than 1600, because other things dragged on for a month before moving, but he didn't refund the money, and he didn't come to a new place to hook up, saying there was no host. As a result, 1600 yuan was spent for a month, which was really a pit. But it's no use looking for it several times. I have to admit that I'm unlucky and I don't trust these small companies anymore.
