Depump is a word jokingly called by netizens, but it should actually be Quanjude.

Quanjude is a time-honored Chinese brand, founded in 1864 (the third year of Tongzhi in the Qing Dynasty). It has achieved considerable development after several generations of entrepreneurial struggle. In January 1999, "Quanjude" was recognized as a "well-known trademark" by the State Administration for Industry and Commerce, becoming the first Chinese well-known trademark in the service category in China.
