What does the word "truth" commonly used in the Book of Changes mean? Please explain in detail.

In academic circles, the meaning of "chastity" in the Book of Changes has always been controversial.

Mainland scholars are mostly trained to "ask questions, ask questions". However, Zong Yirao believed that some chastity should be trained as divination, and some chastity should be trained as duty, correctness or decision. Shulai believes that the correct explanation should be "people experiment in order to explore the right path"; Ni Dewei believes that it should be interpreted as "formally acknowledging the correctness of divination results"; Loughborough's understanding can be translated as "the main ceremony occupies the instrument"; Kenichi Takashima believes that training should be "positive", that is, "positive words".
