The reason why Quanjude burritos are bitter is a matter of personal taste. Quanjude is a time-honored Chinese brand. It was founded on the sixth day of the sixth lunar month in 1864. Quanjude opened its first roast duck shop on Qianmen Street. After several generations of entrepreneurial struggle, it has achieved considerable development. In January 1999, Quanjude was recognized as a well-known trademark by the State Administration for Industry and Commerce. It was the first Chinese well-known trademark in the service category in China.
