Houlong Red Heart Sweet Potato (commonly known as Houlong Red) produced in Houlong Natural Village, Feng Tang Town, Chaoan County is a famous local specialty. Its potato meat is as red as vermilion, as fragrant as ling and as sweet as honey. And it's softer and less rotten when cooked for a long time. After harvest, longhong sweet potato, tuber and root are stored together, hung on the beam to ventilate or cellar, and stored for many years, which has the best taste. It is said that it was once used as a tribute to Emperor Jiajing and Qianlong, and also as a gift to President Mao Zedong. It is famous! The authentic origin of Houlonghong sweet potato is in the "Shilong" dry land in front of Houlong Village, and the best holy land is in six-thirds of Fanbaoshan Temple (one point, three points). The quality of Houlonghong sweet potato produced here is the best. It is said that Jiajing, Emperor Qianlong and Hou Longhong, both tributes to Chairman Mao, came from here, and their cultural connotations are extremely rich.
