Eating zongzi during the Dragon Boat Festival is a traditional custom in China. Hiragi leaves, Indocalamus leaves or Phragmites australis leaves are mainly used to make zongzi, which are collectively called zongzi leaves. The traditional form of zongzi is triangle, which is generally named after the inner pulp. Zongzi has many shapes, which reflect different regional characteristics. Zongzi not only has many shapes, but also has different varieties. Because of the different flavors in different parts of China, there are mainly two kinds: sweet and salty.
