The four-line limerick written by the old naughty boy is as follows:
1. The old husband and wife depend on each other, you help me to support and love each other, and you and your son wipe the old man’s hand, and we share the joy and happiness It’s a journey of hardship.
2. The childlike innocence of the old naughty boy is still there. He entertains birds and plays with insects. He dances with butterflies and is not lonely. He is charming and smiling.
3. Life is not easy, so why bother to be sulky every day, live in a snail's nest with the door closed and always have a fire, but when you open the window, you will always see a new world.
4. I used to be very frivolous when I was young, but now I am old and have frost on my temples. I am blooming casually, and the sunset is brilliant and beautiful.
