(Before, because of the two ADSLs of China Telecom and China Netcom, I bought a wireless router with a friend, one connected to China Telecom and the other connected to China Netcom. It was also possible to quickly switch between China Telecom and China Netcom. It was cancelled. The room that everyone rented from scratch was three bedrooms and one living room. The area was relatively large and the structure was relatively complex. My friend lived in the first room.)
