Mid-Autumn Festival is a Chinese traditional festival. September 10 is Mid-Autumn Festival this year. Of course, the festival is different every year because Chinese people use the Chinese lunar calendar. It’s always on the 15th day of the 8th month. People usually have a big meal with their family on this holiday. Mooncakes is festival food. It’s a round pastry and there are many different fillings. People used to love mooncake, but now more and more people didn’t.
