Introduction to shepherd's purse eggs: The folk custom of "cooking eggs with shepherd's purse on the third day of the third lunar month" has a history of thousands of years in the ancient city of Qianyang. Legend has it that this custom is related to the famous eunuch Gao Lishi of the Tang Dynasty. According to the "Qianyang County Chronicle" recorded during the Tongzhi period of the Qing Dynasty, in the first year of the Shangyuan Dynasty (760 AD) by Emperor Suzong of the Tang Dynasty, Gao Lishi was framed and exiled to Wuzhou (today's ancient city of Qianyang). On the third day of March of the following year, when he was out of the city for incense, he found that the suburbs were covered with shepherd's purse, but no one was picking it. Gao Lishi was well aware of the nutritional value and medicinal effects of shepherd's purse, so he picked shepherd's purse and boiled it with eggs to make delicious shepherd's purse eggs and shared them with the people. Since then, the residents of Qiancheng have passed down the custom of eating shepherd's purse eggs on the third day of March.
