The Chinese idiom 義無返顧 (yì wú fǎn gù) advises people to “do what is right without hesitation.”
The idiom originates from a passage in the “Biography of Sima Xiangru” (司馬相如列傳), a chapter in “Shiji” (史記), or “Records of the Grand Historian,” written in the early Han Dynasty by the famous historian Sima Qian (司馬遷).
