1. In the south, zongzi leaves, glutinous rice, meat, mushrooms, egg yolk, mung beans and other materials are generally indispensable for making zongzi, but in different parts of the south, the selection of materials for zongzi is also different. We take Guangdong Zongzi, Jiaxing Zongzi and Shanghai Zongzi as examples.

2. Guangdong Zongzi is a representative variety of southern Zongzi. Not only during the Dragon Boat Festival, but also in daily life, Cantonese people often eat zongzi. In addition to the necessary rice leaves and glutinous rice, Guangdong Zongzi often uses salted egg yolk as its main material, and barbecued pork, diced chicken, diced duck, mushrooms, egg yolk, mung beans and peanuts are also its main materials.

3. Jiaxing Zongzi has a very long history, and its fresh meat Zongzi is known as the "king of Zongzi". The general materials are zongzi leaves, glutinous rice, pig hind legs, bean paste and white wine.

4. Shanghai Zongzi is soft and glutinous, with strong flavor, many varieties and rich materials. In addition to glutinous rice, there are fresh meat, chestnuts, mushrooms, egg yolk, roast duck, rice grains, red beans and other common materials in cities.

Because there are many kinds of zongzi, and the materials used in different varieties are also very different, it is difficult to have a standardized answer. As far as southern zongzi is concerned, the common materials are glutinous rice, meat, mushrooms and mung beans.
