马到成功
Meaning
Success upon the horse’s arrival; immediate victory.
Character by character
Origin and story
literaryThe expression appears in Yuan drama, where martial characters speak of winning as soon as their horses arrive. In Zheng Tingyu's Chu Zhao Gong (楚昭公), a character vows revenge for his father and elder brother and confidently anticipates returning in triumph. Zhang Guobin's Xue Rengui (薛仁贵) likewise uses the phrase in a boast about military skill and courage.
These are documented literary uses of a compact battlefield image, not proof that one unnamed general always won upon arrival. The horses suggest the swift advance of a campaign. The idiom later became a general wish for prompt, smooth success, so it can naturally accompany someone setting off on a new assignment or undertaking.
