A Taoist high school text reads, "A seven-year-old child died and he lived for a long time."
Zhuangzi once said: Qi's life and death are the same, and Peng's injury is the same. This sentence explains the attitude of Taoism and even Taoism towards life and death, that is, 800-year-old Peng Zu is the same as a baby who died young. Then you can explain the sentence "when a seven-year-old child dies, he lives long".
