When Mr. Ji was very young, he was clever and naughty, and often made the teacher laugh and cry (the teacher's surname was Shi); One day, Ji Xiaolan took a little yellow bird to school to play. Just as he was having fun, Teacher Shi came in. Ji Xiaolan immediately hid the bird behind the loose brick on the wall. Teacher Shi also saw it. He pretended not to know and went to class. However, when Mr. Shi walked to the wall with a poem, he suddenly pushed the brick back with his hand, and the poor bird was crushed to death. The teacher also proudly sings:
"Good feathers and good birds die after bricks."
