Release background

1956, after the central government issued the call of "marching into science", the editors of children's publishing house, one of the only two professional children's publishing houses at that time, were deeply encouraged and bent on producing some good children's popular science books, breaking the current situation that popular science books were either thin or scarce at that time. But in 1958, they experienced an unforgettable "Great Leap Forward" like the people of the whole country, because they were unsuccessful in all aspects.

From 65438 to 0959, they set out to write a set of natural science encyclopedias to answer various questions for high school students and junior high school students. After a period of soliciting contributions, they gradually established the editing idea of breaking through textbooks and classroom teaching, and set the tone for the editing of 100,000 books in the future. 100,000 Why has become one of the most famous popular science reading brands in China.
