Thinking of the reasons why ancient sages founded gossip and books, I learned the natural form from the mountains and rivers of heaven and earth, the measurement of latitude and longitude from the sun, the moon and stars, the resignation from the appearance of flowers and trees in the clouds, the difference between emotions and sorrows from people's noses and mouths, the truth of flexion and extension from insects, fish and beasts, and the pendulum and opposition from the teeth of bones and horns. Everything changes with the heart, which can be said to be a mastery of the nature of heaven, earth and human beings, gathering and storing the modality of everything ~!
Something like this.
