Are there any interesting composition topics?

An interesting thing is that once, I went to live with my grandfather. One noon, grandpa hummed a ditty and took a lunch break in a chair. Grandpa likes Peking Opera very much and wants to be a Peking Opera actor. I think I will help him realize this wish! From the beginning, I took out the ink and marker from the drawer, and everything was ready except the east wind-when grandpa was asleep. At two o'clock in the afternoon, I waved in front of my grandfather and made sure he was asleep before I dared to touch my hand. I dipped my brush in ink and got it ready. I thought: What are the faces of the actors who sing Beijing Opera? At this moment, I think that face must look like a clown. I started painting. First draw a circle on the nose with a red watercolor pen, and then draw two dark circles on the eyes with ink. At first glance, it looks like a living invincible giant panda! I am very satisfied with my masterpiece. Grandpa woke up. I asked him to sing Beijing Opera, and he hummed a few ditties. When my father saw him, he smiled from ear to ear. At this time, my mother came, and when she saw him, she even leaned over and laughed. Grandpa is a monk named Zhang Er, wandering at sea. I asked grandpa to look in the mirror, and grandpa went to look in the mirror. When he saw him, he laughed with us. Students, do you think this is funny?
