From
李宝嘉 's late-Qing satire
官场现形记 ('Exposé of Officialdom'), Chapter 2. Imperial-era officials traveled with attendants who banged gongs (
锣) and shouted (
喝) to clear commoners off the road - the higher the rank, the longer the gong sequence. Lu Xun reused the phrase mockingly in his 1935 essay
隐士.
