The two towns of Rendong and Renhou in Yulin City have been rich in fragrant garlic since ancient times and have been planted for more than 1 years. According to the records from the Song Dynasty to the Daoist period (995~997), Rendong produced more garlic. "The garlic seedlings are fresh and tender, with rich flavor; Garlic is pungent, anti-inflammatory, stomach-regulating, middle-warming, and poisonous gas. " Rendongda garlic has a pungent smell and is rich in nutrients such as protein, fat, sugar, calcium, iron and vitamins A, B and C, and has high medicinal value. Its head is big, its petals are firm, it is spicy and juicy, its meat is crispy and fragrant, and its stem skin is mostly purple and white.

garlic in Rendong is cold-tolerant, and likes soft sandy soil. It is necessary to keep the soil moist during the growth period of seedlings and garlic. It is planted in winter every year and harvested in spring and summer the following year. The fragrance of garlic in Rendong is formed by the unique geographical, climatic conditions and cultivation methods in Rendong. Rendong and Renhou's soil and water are rich in selenium, so the garlic planted on this soil and water contains high selenium, which is one reason why Rendong garlic is particularly spicy. Secondly, for thousands of years, Rendong has planted rice and garlic in turn, and two crops of rice and one crop of garlic have turned into natural organic biological potassium fertilizer, which is very beneficial to the absorption of garlic seedlings and does not hurt the roots. This is also a "secret" of Rendong's garlic fragrance. According to Yulin's local historical records, from the Qing Dynasty to the Republic of China, most of Rendongda's garlic was transported overseas by Nanliujiang via Beihai, and it was exported to 5 tons in 1932. According to "Guangxi Famous Brand Records", in 195s and 197s, Yulin fragrant garlic was purchased, transported and sold by the state-owned local products department, and sold well in the material fairs in central and southern Guangxi over the years, with products in short supply. Since the 198s, the average annual export is 2,43 tons, with the highest annual export of 4,834 tons, which are exported to the United States, Western Europe, Japan, Hong Kong and Macao and other countries and regions.

in November p>25, Yulin fragrant garlic was certified as a pollution-free agricultural product by the Agricultural Products Quality and Safety Center of the Ministry of Agriculture. In September 26, it was rated as a high-quality agricultural product in Guangxi, and in March 27, it was protected by national geographical indications.
