Mencius once said this sentence in Gao Zi Shang: Reason and righteousness please my heart, and meat please my mouth. This statement is truthful, exquisite, and quite enlightening. The practice of life has also been told time and time again. We, all the reason that fits my heart, always explain the profound things in a simple way. For example, chu huan means that delicacies such as beef and mutton fits my taste. maybe the speaker is sincere, but the listener doesn't care, or the speaker is hoarse and the listener is sleepy. After all, the appeal does not depend on the high voice, let alone the power of the microphone, but should be as dazzling, eye-catching, beautiful and enlightening as the peacock opens the screen.
The emphasis of this text is to talk about art and make the principles easy to accept.
