One day, Ji Yun and several colleagues were talking and laughing with bare arms in the study. Suddenly, Qianlong walked out of the inner palace and went straight to the study. Colleagues saw it from a distance and quickly put on their clothes. Only Ji Yun was short-sighted and didn't realize it until Ganlong came to him, but it was too late to get dressed. In desperation, he hid behind Qianlong's seat, panting and afraid to move. Gan Long sat for two hours without talking. It was a hot summer, and the heat in Ji Yun was unbearable. He poked his head out to spy and asked his colleague, "Is the old man gone?" After listening to it, Qianlong felt bored and laughed, and his colleagues couldn't help laughing. Gan Long finally said, "Ji Yun, you are so rude. How can you say such frivolous things! Why do you call me "old man"? If you explain it properly, I will forgive you, or I will cut your head off! " Jiyun said, "I'm naked. Qianlong ordered the eunuch to help him put on his official clothes. Gan Long asked again in a stern tone, "How do you explain the word' old man'? ! "Ji Yun unhurriedly took off his hat and kowtowed and explained," Long live your majesty, this is called' old age'; You are indomitable and supreme, which is called' head'; Heaven and earth are the parents of the emperor, so they are called' sons'. " The clever compliment was answered correctly, and Ji Yun was forgiven for laughing.
