How to set the weather time of oppo mobile phone desktop calendar?

Now the oppo mobile phone uses the deeply customized color os system based on the Android system, so it is still an Android machine. Therefore, the calendar, weather and time settings are the same as other Android phones:

Calendar/Time: System Settings-General-Date and Time. You can enter what you want here. If you don't go abroad and use Beijing time, it is recommended to turn on the "automatically determine the time and date" option, and the network will be updated automatically.

Weather: There is a weather forecast icon on the home page of the factory. Click it to set it.
