Reveal your true feelings without any falsehood.
Thinking without evil comes from "The Analects of Confucius: For Politics", which is the view of Confucius, a thinker and educator in the Spring and Autumn Period of China, in his evaluation of "The Book of Songs".
Due to the influence of Confucius and the Book of Songs on the history of Chinese thought and culture, people, including contemporary young people, have interpreted this point of view in various ways. "Thinking without evil" can be said to others. Thoughts, wishes in the heart.
There is nothing wrong with being brave enough to express your wishes and thoughts to others. Zhu Xi placed this sentence in the second chapter of "Wei Zheng", quoting Confucius's evaluation of the Book of Songs to tell those who work in politics to be open-minded and aboveboard.
"Si Wu Xie", Yang Bojun's "Translation Notes" said that "Si" is an unintentional phonetic word, which originally has no meaning. It was Confucius' original interpretation of it as "thought". Yu Yue, a native of the Qing Dynasty, also said this in his "Quyuan Miscellanies·Shuoxiang". I agree with their point of view in the note and follow it.
