According to Baidu's encyclopedia, you can get candy by participating in the Full Moon Night event. The Full Moon Night is a traditional festival event usually held on the 15th day of the 8th month of the lunar calendar every year, where people will enjoy the moon, eat mooncakes, hang lanterns and so on. At the same time, many businesses or communities will also organize activities, such as lion dance performances, lantern riddles, etc., in which candies will also be given away.
