It is said that people's eating habits of vegetables and boiled eggs on March 3 are related to the famous doctor Hua Tuo. Once Hua Tuo went to a place to collect medicinal materials, and it was raining cats and dogs. He went to an old man to take shelter from the rain. Hua tuo looked very pitiful when he saw the old man in his home. In order to thank him for letting him into the house to take shelter from the rain, he offered to see the old man. When he found that the old man often had headaches, he told him to put vegetables and eggs together.

Ground vegetable is a kind of wild vegetable, which can be seen everywhere in the field. Because it tastes good and has certain nutritional value, and from the perspective of traditional Chinese medicine, ground vegetables have a good effect on people's spleen and stomach and eyes, and contain a lot of nutritional elements, which can supplement calcium and iron for people. Eggs are nutritious food with low fat and high protein, so the food made of these two ingredients is definitely good for people's health.

Many people like to eat local dishes, and local dishes can also be made into many delicious foods, such as making jiaozi, making noodle boxes, or making pot stickers and so on. Because of the cold weather in the north, there are few vegetables in winter. Northeasters also like to pick local dishes in spring, blanch them, make them into jiaozi, put them in fresh-keeping bags and freeze them in the refrigerator, and take them out in winter to make buns and wrap them in jiaozi.

However, local dishes are not suitable for everyone, such as pregnant expectant mothers, because eating them will be bad for their babies and may lead to miscarriage, so families need to pay special attention not to let expectant mothers eat such foods.
