Hohhot students taste their handmade mooncakes on Sept 16. This year's Mid-Autumn Festival falls on Sept 21. The festival celebrates three fundamental concepts which are closely tied to one another: gathering, giving thanks and praying. It is a time for outdoor reunions of friends and relatives. Traditional activities include eating mooncakes, gazing at the full moon and guessing lantern riddles – an activity involving writing riddles on lanterns while others try to guess the answers.
