In the past, Shun wanted to preach to the world with pleasure, so he meant "use". Confucius said: In the past, Shun wanted to spread the teaching of music to the world, so he ordered Chongli to lift Kui into the grass. Shun thought that music was righteous. This comes from the "Cha Zhuan" in "Lu Shi Chun Qiu" of the pre-Qin Dynasty, which means: In the past, Shun I want to use music to spread education to people all over the world. "Lu's Spring and Autumn Annals", also known as "Lu Lan", is a miscellaneous masterpiece compiled by disciples under the auspices of Qin State Prime Minister Lu Buwei. It was written on the eve of Qin Shihuang's unification of China. This book is based on "Taoism" as its main body, and uses the thoughts and theories of famous schools, Legalists, Confucians, Mohists, farmers, military strategists, and Yin-Yang schools as its material, integrating the theories of hundreds of schools of thought into one furnace.
