一言以蔽之 is a Chinese idiom (chengyu) meaning “to sum up in a single word”. To put it in a nutshell; to summarize succinctly. Literally, “To cover it with one word”.
The Book of Odes (Shijing), China's earliest anthology of poetry, comprises 305 pieces. Compiled during the Spring and Autumn period, it is divided into three sections: Feng, Ya, and Song, and has always been highly praised.
When Confucius edited The Book of Odes, he famously commented: 'The three hundred poems in The Book of Odes can be summed up in one sentence: their thought is entirely pure, without any evil.' This statement is the origin of the idiom '一言以蔽之' (yī yán yǐ bì zhī), meaning to sum up in a word.
