How does Apple's mobile calendar display the 24 solar terms?

1. Take Apple 7 as an example. First, open Calendar on your phone.

2. After opening, click the "Calendar" option at the bottom of the interface.

3. After entering this interface, check "China Holiday".

After that, we can see that there will be a "dot" under some numbers, such as March 20th.

5. After clicking, you can see that this day is the "vernal equinox".
