Soy sauce and other processed foods made by Gulong Co have been a common sight on the tables of Xiamen residents for decades. 

The time-honored brand used its popularity to create a sauce culture park in 2011, where an exhibition center and an open space drying field have attracted numerous visitors from home and afar. 

Over 3,000 tons of soy sauce is produced in the park every year. About 80 percent of it is used as the key ingredient in Gulong's braised pork in brown sauce, the most popular food in Xiamen, while the remainder is used in various other dishes.
