The vital name of the book "One Hundred Thousand Whys" is taken from Yilin's work, and Mi Yilin is taken from a sentence of Lou Kipling, the British writer who won the 1907 Nobel Prize for Literature: "Five thousand wheres, seven thousand hows, and one hundred thousand whys." Mi Yilin's works are models of excellent popular science works and have had a great impact on the world of popular science creation in my country. Mi Yilin is good at combining literature and science. He uses literary style, vivid metaphors, typical examples, and poetic language to describe scientific knowledge eloquently. His works are lively and logically rigorous.
