Zhuang Sheng was obsessed with butterflies in his morning dream, and looked forward to the emperor's spring heart with cuckoos. Zhuangzi Dreams of Butterflies Once Zhuangzi was sleeping, he suddenly had a strange dream. In his dream, Zhuangzi turned into a beautiful butterfly. It flew east and west for a while, dancing gracefully among the grass and flower branches. Speaking of happiness, it was extremely happy! The butterfly that Zhuangzi became just kept flying around, completely forgetting that he was Zhuangzi. It was playing vigorously when it suddenly woke up. When Zhuangzi saw that he was still lying on the bed, he realized that the butterfly was not him. He was a human being, Zhuangzi. But Zhuangzi suddenly felt that this might not be right: he might have been a butterfly! He was dreaming, and he became Zhuangzi in the dream! Then he thought, this may be wrong: he was obviously Zhuangzi, and he must have been dreaming just now. ! In this way, Zhuangzi thought this way for a while, and thought that way for a while. After thinking about it over and over again, he couldn't figure out whether he was Zhuangzi or a butterfly. A king of Shu in ancient times descended from the sky and became the king of Shu, named Emperor Wang. When Emperor Wang was king, he was very concerned about the lives of the people, taught them how to plant crops, and told the people to follow the farming season and do a good job in production. He loves the people, so the people support him very much. After Emperor Wang died, his soul turned into a cuckoo. He loved the people during his lifetime, and after his death he still cared about their lives. Every Qingming, Guyu, Beginning of Summer, and Xiaoman, he would fly to the fields and chirp loudly. When people heard this voice, they all said: This is our Emperor Wang Du Yu! So they remind each other: It’s time, so plant seeds quickly. In other words: It’s time to plant the rice seedlings. Therefore, people also call the cuckoo a robin or a work-inducing bird.
