How about Dr. Peng's broadband in Shanghai? For those who have used it, it is 2.5 million.

There is no difference between 2.5M and 2M, so it is recommended to use big brands. Don't worry, telecom or Unicom will do. Telecommunications are generally in the south. Miscellaneous brands, such as Tietong and Bailing, are bad and unstable. They enjoy bandwidth, which is fast when there are few people and slow when there are many people. Therefore, it is generally not needed, especially when playing games. Many people have too many cards and want to die. So let's use a stable one.
