　　Pujiang Ugly Citrus is a specialty of Pujiang County in Chengdu, Sichuan.

　　Known as "Ugly Citrus" in Chinese, its scientific name is "Hyuganatsu," and it is also referred to as "Dingding Citrus," "Ugly Tangerine," "Ugly Eight," and other names. It was developed in 1972 by the Japanese Ministry of Agriculture, Forestry and Fisheries Horticultural Research Station through hybridization of the Kiyomi and Nakano No. 3 citrus varieties. It was first introduced to Pujiang County, Sichuan Province, for cultivation [1], with the county achieving single-tree yields exceeding 5 kilograms by 2003, peaking at 15 kilograms. In 2003 alone, over 1,000 visitors came to Pujiang to study its cultivation. Later, neighboring counties such as Jintang and Danleng in Sichuan, as well as Neijiang in Sichuan, Chongqing, Yunnan, Jiangxi, Hunan, and Zhejiang, gradually began limited planting. Through high-grafting techniques, the Hyuganatsu citrus grown in the western Sichuan basin produces large fruits, averaging 200 grams with some reaching over 400 grams. The fruit is oblate in shape, often featuring a short protruding neck. The peel is yellow-orange, beginning to color in early October and fully ripening by early December. The skin is slightly rough but easy to peel, and the juice has a sugar content of over 13%, reaching up to 17%, with an exceptionally sweet flavor. The fruit matures between February and March of the following year, boasting excellent taste.

　　The jurisdiction of Pujiang County, Chengdu City, Sichuan Province, includes 7 towns, 4 townships, and 1 subdistrict (Heshan Subdistrict, Shou’an Town, Xilai Town, Chaoyanghu Town, Datang Town, Daxing Town, Ganxi Town, Chengjia Town, Baiyun Township, Guangming Township, Changqiu Township, Fuxing Township)
