There is no China integrity in Samsung's mobile phone calendar.

Sorry, because I'm not sure about the specific model of your mobile phone. If it's an Android smartphone, the calendar that comes with the mobile phone usually has China solar terms. It is suggested that you refer to the method of setting solar terms in China with note3 mobile phone: Touch the mobile phone application -s calendar, select the month view after entering, and touch the mobile phone menu button-Calendar-Twenty-four solar terms to display it.
