I have always wondered why the Mid-Autumn Festival falls on the 15th day of August every year. The moon is obviously round on the 15th day of every month.
The first time I knew this was when I was in the third grade of junior high school. At that time, I thought I could only see the full moon once a year, and I thought it was extremely precious. That night, I seemed to have to go to evening self-study or something, I can't remember clearly. Anyway, I complained to my classmate: "We can't enjoy the full moon this year. We have to wait another year." She looked at me as if I was looking at something and said, "Please, sister! The moon is full on the fifteenth day of every month! You don't have to wait until next year!"
