Why is there no notice of fog and haze in my mobile phone weather forecast?

The weather forecast in the mobile phone (Sina weather) belongs to widget.

If your machine is Android 4.0 or above, please do the following:

1. Click the application in the lower right corner of the screen on the standby desktop of the mobile phone to enter the application page.

2. On the application page, click the widget at the top of the screen and slide the screen to find the Sina weather widget. Hold it for a long time and drag it back to the desktop.

The answer is not easy, I hope I can help you, please help me adopt it if you are satisfied, thank you!
