Influenced by eating habits. Zongzi can be used as a staple food in the south, and the common one is salty zongzi made of meat and rice. But in the north, zongzi is regarded as a snack during festivals, and sweet zongzi is more common in general. The relationship between primary and secondary roles in food; Simply put: the staple food is salty, and the complementary food is sweet. The south is rich in rice, and the daily staple food is white rice, and zongzi naturally becomes the staple food; The north is rich in wheat, and the daily staple food is white steamed bread. Zongzi, which is made of rice, has evolved into a snack these days during the Dragon Boat Festival. So in the south, such as Fujian, you can buy zongzi every day twenty or thirty years ago, but not in the north.

Factors of different uses of food; Zongzi is the festival food of Dragon Boat Festival, which is mostly used for special festival activities such as sacrifice. Since it is a formal and important activity, of course, some valuable elements should be put in. Everyday in the north, there is little sweetness, so you should eat something sweet after the holiday; The south is a sugar-producing area, which is relatively rich, so eating sweet food is more daily. After a holiday, you should eat hard vegetables. Meat is more luxurious than sugar. So there are red dates and red bean paste in jiaozi in the north, and bacon, ham and salted eggs in jiaozi in the south.

Of course, the more developed the economy and logistics are, the better, and the regional differences are getting smaller and smaller. Eating salty or sweet is often caused by eating habits. One side of the soil and water raises one side! Saltiness and sweetness are the characteristics of each region! I can eat salty and sweet! I love tofu brain, both salty and sweet! Do you think I should be a southerner or a northerner? I don't think this should be absolute. North and south have different eating habits and tastes. Most southerners like to wrap meat, egg yolk and red beans in zongzi, and add some salt to make it taste better. This is just a habit. If we northerners grew up in the south, we wouldn't like to eat sweet zongzi like southerners. In the final analysis, different regional cultures lead to different customs and cultural characteristics. One side breeds the other.
