Founded in 1956 as Kaiping Sauce Factory, Weishida is now a brand of Fuda Food, a subsidiary of Heinz Group, and has been rated as "Consumers' Favorite and Most Reassuring Condiment" by the China International Condiment and Food Ingredients Expo for four consecutive years, with a market coverage rate of 68% in the country, and is a household name in Fujian, Guangdong, Zhejiang and other regions.
 
Weishida has only one very fresh oyster sauce, the oyster juice selected is made by slow boiling of oyster meat, but the concentration is only 15%, which is thinner than most brand products, due to the addition of a certain amount of white sugar, the sweetness is higher, more suitable for mixing and thickening, and the price of 510g is not cheap at 10.5 yuan.
 
The fact that Weiji Oyster Sauce has been able to enter the consumer eye and has a high level of recognition is largely due to Weishida's own brand reputation and leading position in umami soy sauce, while the oyster sauce itself has performed poorly.
