How does Apple's mobile calendar show the legal holidays in China?

1. First, click the "Calendar" icon button in the main screen interface.

2. Enter the calendar page and click the "Calendar" button below to enter the open system interface.

3. Click China Holiday, check the China Holiday button, and the system page will display subscribed.

4. Click on the message icon at the back, and choose the color of China holiday tips.

After clicking the finish button, I found that some dates have "gray dots" under them.

6. For example, click 201810/0 month 17 to find the system page as shown below, that is, the setting is complete.
