How did the custom of boiling eggs on March 3 come about?

According to legend, in Chu, people have headaches because of wind and rain. On the third day of March, Shennong passed Yunmengze and saw that the villagers had a terrible headache. He found wild eggs and vegetables and cooked them to satisfy people's hunger. When people eat it, their heads won't hurt. The custom of "eating vegetables and boiled eggs on March 3 can keep them from having headaches for a year" has continued to this day.

Scientific research has proved that cauliflower has a good effect on treating headache and can prevent meningitis. People discovered this effect a long time ago. Every year in the third month of the lunar calendar, cauliflower blooms. Every year in the third month of the lunar calendar, everyone will collect cauliflower and boil eggs to eat. Over time, this has become a custom. In order to remember and inherit this fine tradition, people set the third day of March as cauliflower eating day.

Eating cauliflower and boiled eggs on March 3 is not only in Hunan, but also in the southern, central and north-central regions.
