Zengcheng lychee, a specialty of Zengcheng City, Guangdong Province, is a national geographical indication product of China. According to legend, He Xiangu, one of the Eight Immortals, was a native of Xiaolougui Village, Zengcheng. When He Xiangu was 15 years old, she received enlightenment from an immortal and learned the magic of flying by eating mica pieces from Phoenix Mountain. When she was 18 years old, her parents betrothed her to someone else, but He Xiangu disagreed. On the eve of the wedding, she flew to Luofu Mountain without anyone noticing and became an immortal. Later, because he never forgot the intoxicating lychee fruit in his hometown, he often returned to his hometown and strolled in the lychee garden. One day, He Xiangu was nostalgic for the beautiful scenery of lychees in the West Garden. She sat on a branch and knitted a belt. When she left, she left a green silk thread on the tree. The green thread floated around the lychees, so there was a green thread on the lychees, and people gave it to them. Named "Hanging Green". It can be seen that "hanging green" is magical and precious, with an extraordinary "fairy spirit".
