What broadband service does everyone use in the first phase of Xinkangyuan in Xisanqi?

First of all, you consult the property and see where the cables in the community are buried. Secondly, I'm using Skyworth broadband, with a bandwidth of 4M, and 99 yuan for one month. If I use it for a long time, I saw that it was only over 50 months in four years when I paid the bill yesterday. The actual network is in good condition, and the download peak is 400 K/s.
