Please summarize the origin of the early word in concise language and tell me what you understand from it.

The origin of jujube: Lu Xun's father was ill. He was very tired when he took care of his father and went to school. On one occasion, Lu Xun was late. Under the guidance of Mr. Shou Jason Wu, he went back to his desk and carved a small early word on it. Since then, he has never been late again, and he has always been early, doing everything early and struggling all his life. The truth I understand is that we should be the first branch of the east wind, like Lu Xun, Xi Chun and Zao Chen.
