Problem description:
Is there a website where you can check your daily work? Is there any other way?
Analysis:
You have to look at the perpetual calendar to find the stem of the sun. If you count eight characters, you'd better have time. When you look at the moon column, you should pay attention to whether you pay attention to the solar terms, because the division of months is based on the solar terms in the twenty-four solar terms. Pay special attention when looking up eight characters.
