Yunnan Qujing broadband which is good?

Qujing broadband is best to use telecommunications. I am in the industrial technical school next to the shirt factory. The Tietong I used failed to go online the day before yesterday. This is just established. Although it's cheap-666 yuan a year, I also gave 120 yuan's mobile phone bill, but the network speed is too slow and it is often disconnected. Telecom is a little more expensive than Tietong, but it doesn't break down often and its network speed is fast. Regret using Tietong, and change the telecom after the expiration! I advise you not to use Tietong, it's too late to regret it.
