Zhijiang Unicom's network is really poor. The main reason for poverty is not the technology of FTTH and FTTB. The residential fttp is actually the operator's large LAN. For example, the uplink bandwidth of 10 people is 100M, and everyone is very fast, but what about 100 people? The outbound bandwidth of Zhijiang Unicom is the biggest bottleneck, and the more FTTH users, the slower. In addition, if the landlord doesn't want to use 8M ADSL, the telecom company is engaged in FTTH recently, so you can try it.
