In the Ming Dynasty, there was a county magistrate named Gao in Shaoxing, Zhejiang Province. He was a big corrupt official who was hated by everyone. This year is Gao's birthday. He had no ink in his chest, but he insisted on showing off and invited a group of literati to entertain him. Famous talents in Jiangnan have also received high invitations. He thought, just waiting for an opportunity to tease corrupt officials and invite him to Gao Fu. Before the banquet, Xu Wenchang proposed to write a congratulatory poem for Kochi Prefecture. Hearing this, I was very grateful and hurriedly ordered someone to take out paper and ink. Xu Wenchang raised his pen and dipped in ink: Longmen has one arch and two arches, and Cui Lin has three arches and four arches; Take off your yellow robe when you go to Cuilin, and you can drive away the clouds by taking off your yellow robe. I was very proud of the first sentence I read in high school. After reading the second sentence, he was happier. He felt that this piece of green forest was only available in the Yaochi of the Queen Mother, so he continued to look down. He couldn't help changing his face. He was about to get angry when he saw the fourth sentence and repeatedly said to Xu Wenchang: OK, OK; Not only poetry is good, but also calligraphy is better. Tell people to get on the horse quickly. He wants to hang it in the hall. After the banquet, all the guests walked out of the tall house. Xu Wenchang said to everyone: My humble job is actually a mysterious poem. Then I'll tell you the answer. Everyone laughed and called Gao a big fool.
The answer is: cicada. Because cicadas can climb trees (three arches and four arches on the green forest), they will shed their skin after climbing trees (take off their yellow robes on the green forest) and fly after shedding their skin (take off their yellow robes to drive away clouds).
