　　Longli Pea Shoots: In Longli County, the large temperature difference between day and night in winter reduces the likelihood of pests and diseases, and the resulting shoots are characterized by emerald green leaves, a pleasant aroma, a melt-in-the-mouth texture, and a sweet aftertaste. According to the Guizhou Agricultural Chronicles, before 1943, Longli had already begun trial planting of pea shoots. By the early 1960s, after extensive trial experiments, Longli Pea Shoots started to be promoted for wider cultivation—boasting over 50 years of planting history. The shoots are sold to Hong Kong and Macao, with the highest retail price reaching 268 Hong Kong dollars per jin (500g).
