The origin of Tomb-Sweeping Day's eating youth league;

One year in Tomb-Sweeping Day, Li Xiucheng, the general of Taiping Heavenly Kingdom, was hunted down by Qing soldiers. A farmer nearby came forward to help, disguised Li Xiucheng as a farmer and cultivated land with him. The Qing soldiers didn't catch Li Xiucheng and didn't stop there, so they added soldiers to set up posts in the village, and everyone who left the village had to be inspected to prevent them from bringing food to Li Xiucheng. ?

When the farmer came home, thinking hard about what to bring to Li Xiucheng, he slipped on a clump of wormwood. When he got up, he saw that his hands and knees were stained with green. I immediately picked some wormwood and went home to wash, boil and squeeze it into juice, and kneaded it into glutinous rice flour to make zongzi. Then put the green jiaozi in the grass and mix with the sentry at the village entrance.

Li Xiucheng ate the green ball, and felt that the fragrant glutinous rice was not sticky. After dark, he bypassed the Qing army post and returned to the base camp safely. Later, Li Xiucheng ordered the Taiping Army to learn to be a youth league to defend itself against the enemy. The custom of eating dumplings spread.
