How does Huawei mate9 set up double weather?

Open the weather and click the city icon > desktop weather. In the resident city area, click Add City, directly select the city in the list or search for the city to be added through the search bar.

When the current location is different from the permanent city, the desktop weather will automatically display the weather in the twin cities.

When the current location is consistent with the resident city, the main screen only displays the weather of one city.
