Originating from Beijing, jing jiang rou si is a trademark of the capital's extraordinary cuisine, consisting of sliced pork meat cooked in a sauce based on sweet beans. The dish is then traditionally rolled in soya bean wraps, although it can be wrapped in any type of pancake.

The dish is reddish in color due to the distinctive Beijing sauce in which it's cooked in, and is usually garnished with chopped green onions or shredded leeks. There are also some regional varieties of the dish with either sha cha sauce or hoisin sauce replacing the sweet bean sauce in the process.
