The idiom 半途而廢 (bàn tú ér fèi), “give up halfway,” or leave something unfinished, originates from “The Doctrine of the Mean (1),” one of the four Confucian canonical scriptures.
The idiom “pulling up seedlings to help them grow” originated from an article by Meng Zi(1) (also known as Mencius) who was one of the great philosophers in Chinese history.
