There are telecom and Great Wall options in the community, and it is also fast to query the most stable telecom maintenance service. The Great Wall belongs to the bandwidth used by a residential building in the community. If the residential building is renovated once or twice, it will be terrible if there are many people, hehe ...? It goes without saying.
I use telecommunications now. The price is much more expensive, but it is stable. In the second year, 2200 yuan covers 10M optical fiber, free of monthly rental of landline.
