Half an acre of square pond opened, and the sky was overcast.
How can the canal be so clear? Because fresh water comes from springs.
Philosophy: Taking the pond as a metaphor, it shows that the way to learn is to accumulate and absorb new nutrients continuously. Everything is moving, changing and developing, and everything can maintain its existence only in movement. It is this uninterrupted movement, change and development that things can survive in constant self-renewal. Once this movement stops, things cannot exist. Without the constant renewal and accumulation of knowledge, a person cannot exist.
Qinshi (Song Sushi)
If there's a sound on the harp,
Why don't you ring the bell in the box?
If the word rings on your finger,
Why not listen with your fingers?
Philosophy: Wonderful music is an organic whole, which is composed of several parts and elements that influence and restrict each other. In music and piano sound, fingers, piano, players' thoughts and feelings, playing skills and other parts and elements are interdependent and indispensable, influencing and restricting each other, and are closely related. Materialist dialectics holds that the fundamental content of universal connection is the contradiction between things. So what this song reveals is the contradiction between piano, fingers and the sound of the piano. If the players are included, then the relationship between the players' thoughts, feelings and skills and the piano and fingers can be regarded as the relationship between internal contradictions (internal causes) and external contradictions (external causes). The former is the basis of music production, and the latter is the condition of music production.
