There are also many sayings about the origin of boiled eggs. According to legend, during the Three Kingdoms period, Hua Tuo was caught in heavy rain and came to Miancheng to collect herbs. An old man took shelter from the rain and heard that he had dizziness, so he went to the vegetable garden and picked a handful of shepherd's purse, washed it, mashed it, filtered out the juice and boiled eggs for the old man to eat every day. After a few days, the old man's dizziness was much better, because it was the third day of the third lunar month, so the villagers ate it every year.

As a custom culture, boiled eggs with shepherd's purse has been circulating for a long time, and the meaning here is particularly good, because the homonym of shepherd's purse is "collecting money" and "gathering wealth". Therefore, on the day of ancestor worship on the third day of March, most people will use the aura and wealth of their ancestors to bundle a handful of fresh shepherd's purse into soup and cook it with eggs, so that the whole family will eat a bowl, which means that the whole family will make a fortune.

Having said that, shepherd's purse is not only a delicious food, but also represents a good wish of people. However, from the perspective of traditional Chinese medicine, the biggest function of shepherd's purse as medicine is to dispel the old cold and its medicinal properties are very peaceful. Eating shepherd's purse on March 3 is to dispel the cold accumulated in winter and enhance resistance. Therefore, there is a folk saying that it is also reasonable for adults to eat and keep fit, and to be alert and discerning.
