Yen Chau round mangoes are famously delicious.
Yen Chau district is known as a region famous for its delicious fruits in Son La province, with many developed models such as: mangoes, tissue-cultured bananas, late-ripening longan, and staggered-season plums... Among these, the native round mango is particularly noteworthy, covering an area of about 200 hectares. This is a unique mango variety found only in Yen Chau, dating back hundreds of years. The fruit is only about the size of a fist, with a yellow flesh and a distinctive aroma when ripe.

The festival was organized to contribute to the preservation and promotion of the nation's historical and cultural traditions.
Yen Chau round mangoes have been included in the list of rare and valuable plant genetic resources by the Ministry of Agriculture and Rural Development; it is the only native mango variety in Northern Vietnam listed in the Food and Agriculture Organization of the United Nations (FAO) catalog that needs to be preserved and developed; and it has been granted a Certificate of Registration for Geographical Indication and Brand Identification System by the Intellectual Property Office.
Through investment in fruit tree development and supplying products to domestic and international markets, the lives of people in the area have gradually improved. This year, the estimated total fruit production in Yen Chau is approximately 104,000 tons, generating a value of about 1,000 billion VND, with mangoes, plums, and longan being the main crops.
