The traditional custom of "eating local dishes and boiling eggs on March 3rd". Ground vegetables, also called shepherd's purse, are wild vegetables, but they are rich in nutrients, containing a lot of carotene, B vitamins and vitamin C, and the content of calcium and iron is also relatively high, which has the effects of clearing away heat and stopping bleeding, clearing the liver and improving eyesight, promoting diuresis and reducing swelling. Eggs are rich in protein, lecithin and vitamin A. These two kinds of animals and plants are naturally good for the body. Because the homonym of shepherd's purse is "gathering wealth", people wash fresh shepherd's purse and bundle it into a bunch, add eggs, red dates and ginger to cook it together, peel the eggs and drink soup, which is not only rich and aura, but also can prevent diseases and keep fit. However, it should be noted that red dates should be put after the eggs are cooked, which can not only ensure that the fragrance and medicinal effects of shepherd's purse completely penetrate into the eggs, but also make red dates not rotten, sweet and delicious.
