2. Turn on the personal hotspot function, then set the name and password of the mobile phone WIFI, and then click "Finish" in the upper right corner. Note: you don't need to set a password, but everyone around you can connect to your mobile phone WIFI, and the traffic will soon be gone.
3. Control how many users your mobile phone can connect through "connection management", or pull people who don't want to connect into the "blacklist".
4. After the above settings are completed, you can let other mobile phones or computers search their own WIFI, click Enter, and enter the correct password to use it normally.
