What strange winter vacation homework have you been assigned?

When I was in the fourth grade of primary school, the math teacher Wu Shuo assigned an assignment, which was to go to his house to help move bricks. His family is building a new house, and then he makes his classmates move bricks for a long time in a disgusting way. It happened that he was in math class and physical education class. At that time, he said that whoever moved more would be praised, and then he didn't have to take part in cleaning for a week. He also said that whoever works hard is a good student. Anyway, there are too many disgusting things. I don't know anything in the fourth grade and I am squeezed.
