How about Zhanjiang Mobile Tietong broadband?

Not bad, 6M fiber, all-in-one fiber router, with WIFI. Watching movies and downloading are basically around 500KB~560KB. Just opening the website of the telecom server will be a bit stuck, and other large websites will be fine.

The price is 499 yuan/year, the gift card is 280 yuan, and the phone bill is 120 yuan, which is super cost-effective.

I pulled two mobile optical fibers at home, and then bought a wireless router that can access the power grid and used it. The download volume is about1m.
