What is a local dish:

Ipomoea japonica is a kind of wild plant, which is also called "shepherd's purse" and has rich medicinal value. Ground vegetables, also known as "shepherd's purse", are wild plants that grow green, have white roots and little white flowers. Ground vegetables are a panacea. There is not only a folk proverb that "shepherd's purse is a panacea on the third day of March in the spring", but also a saying that "spring eating shepherd's purse is an elixir".

Origin of the custom of boiling eggs on March 3rd;

During the Three Kingdoms period, Hua Tuo, a famous doctor, was collecting herbs outside. One day, when he was sheltering from the rain in an old man's home, he saw that the old man was suffering from headache and dizziness, which was painful and embarrassing. Hua tuo immediately diagnosed the old man, and collected a handful of vegetables in the old man's garden, asking the old man to take juice and boil eggs to eat. The old man obeyed, took three eggs and recovered. The story spread, and people boiled eggs with vegetables one after another, and the craze spread all over urban and rural areas. Hua tuo treated the elderly on the third day of March, so it became a custom to cook eggs with local dishes on the third day of March. It gradually spread and became popular.
