1. "Song of Music and Learning": "The human heart is naturally happy, and it binds its selfish desires. When selfish desires arise, conscience is still conscious. It disappears as soon as it wakes up, and the human heart is still happy. Joy is to enjoy this study, Learning is learning. If you are not happy, you are not happy. If you are happy, you will learn. If you are happy, you will be happy. I am happy for this.” 2. Knowing something is not as good as being good at it, and being good at it is not as good as being happy. 3. If you learn and enjoy yourself, then you are good. Believe in learning and know the joy of self-satisfaction. Those who like it are like visiting other people's gardens; those who enjoy it will get something for themselves.
