When foreign tourists come to China, they need to rent wifi. Where can I get it?

there are few WIFI networks in China, which are generally found in hotels, guesthouses, airports, stations and other public places. If you want to use the Internet anywhere, the general method is to apply for a China Mobile, China Unicom or Telecom card, turn on the WIFI hotspot function of the mobile phone after plugging it in, and set the password of the WIFI hotspot, so that you have a WIFI mobile device, and your laptop can surf the Internet anytime and anywhere through the WIFI hotspot.
