Compared with telecom, Tietong has a much smaller scale, fewer servers, and the junction boxes are in the open air, all of which are connected by open wires. Of course, its stability is poor, especially when it is windy and rainy, but it also has its advantages, and the price will be relatively cheaper. Telecommunications and optical cables are underground, but the package price is quite expensive. If you don't play online games or speculate in stock futures, you'd better choose Tietong.
