"Eating eggs on the Dragon Boat Festival makes stones rot" means that if you eat boiled eggs on the Dragon Boat Festival, you will have endless energy in a summer and even stones will rot. In fact, this is a bit exaggerated, but the actual situation is that in the past, the life in the countryside was bitter, and basically no meat could be eaten. So on the Dragon Boat Festival, eating boiled eggs can be regarded as supplementing energy for the body.

The legend of wormwood boiled eggs:
As for the folk custom of eating eggs on the Dragon Boat Festival, there is a folk legend: It is said that a long time ago, there was a god of plague in the sky, and every year during the Dragon Boat Festival, he always sneaked into the folk to spread the epidemic. Most of the victims are children, ranging from fever and anorexia to bedridden. Mothers are very distressed about this, so they go to Nu Wa Niangniang Temple to burn incense and kowtow, begging her to eliminate disasters and bless future generations.
When Nu Wa learned about this, she went to the god of plague and said, "You will never be allowed to hurt my first child again." Knowing that Nu Wa had great magical powers, God of plague dared not oppose her, so he asked, "I wonder how many children are there in the lower bound of the Empress?" Nu Wa smiled and said, "I have many children. To tell you the truth, I order my first son-in-law to hang an egg bag in front of her skirt every Dragon Boat Festival. All children who hang egg bags are not allowed to mess around. "
This year's Dragon Boat Festival, the god of plague went down again. I saw a small net bag with boiled salted eggs hanging on the children's chests. The god of plague thinks that they are all children of Nu Wa, so they dare not hurt anyone. In this way, the custom of eating eggs on the Dragon Boat Festival gradually spread.
