Legend has it that one year in Tomb-Sweeping Day, a farmer saved an officer of the Taiping Army. The Qing soldiers searched everywhere. Farmers mix wormwood into glutinous rice flour and make it into a green ball for officers to eat. To commemorate the green ball that saved lives, Li Xiucheng ordered the Taiping Army to learn to be a green ball to defend itself against the enemy. Since then, the custom of eating the Youth League has spread wherever the Taiping Army fought.
