Confucius was very modest and worked hard in his studies. On one occasion, Confucius learned the drum set from Shi Xiangzi. The name of this song is Cao. Confucius practiced hard for many days, and Shi Xiangzi said "OK". Confucius said, "I have mastered the playing method of this piece of music, but I haven't counted it yet." After practicing for many days, Shi Xiangzi said, "Yes, you counted on it." Confucius still said, "No, you didn't achieve your goal." After a long time, Shi Xiangzi thought it was really ok this time, but Confucius still thought that he didn't play this piece well, so he studied it repeatedly and realized the connotation of piano music until he saw the image of King Wen expressed in the music. His spirit deeply touched Shi Xiangzi. Until now, Confucius' famous saying "Never tire of learning, never tire of teaching" is still our motto.
