It's You at the Same Table by Shi and Sun Chen, which is about the changes of primary school students. There is this line when talking about a classmate named Xiaoshi.

Shi: Dear leaders, my childhood dream was to be Qi Baishi. When I grew up, I became a cleaner. Some people say that ideal is far from reality. I said, no, Qi Baishi is just like a cleaner. Thank you.

Sun Chen: Why is he the same?

Shi: When I was young, my ideal was to draw a beautiful tomorrow on the canvas with a small brush.

Sun Chen: Ah.

Shi: Today, I drew a beautiful day on the big canvas of the city with a big brush, so I said Qi Baishi is the same as a cleaner! Thank you, my speech is over.
