Non-music thought: In the Warring States Period in ancient China, Mozi, a representative of Mohism, put forward the thought of "non-attack" and "universal love", in which non-attack means seeking peace without fighting, and universal love means loving the people. However, Mozi also has the idea of "not being happy".

Unhappy, pronounced as fēi yuè. Music is music.

On Mozi's thought of "Flying to Yue", Mozi has a special book, and the existing thirty-two books of Mozi, Flying to Shang Yue, focus on this theory.

The idea of "non-music" is to ban music and oppose engaging in musical activities.

Mozi believes that everything should benefit the country and the people, while the people and the country are struggling for survival. Making musical instruments requires people's money, wasting people's production, and music can also make people indulge in wine and color. Therefore, music must be banned.
