Yao Shuhan took this opportunity to make fun of his parents, saying, "Last time, an insurance salesperson tried to sell something to my parents. At their age, they can no longer buy pension or medical insurance. The person mentioned investing in children's education funds, which worried my parents. They said, look, all our children are of this age, and the youngest grandson can only attend graduate school. Can we directly invest in graduate or doctoral education insurance? That insurance seller was almost struck dumb by my parents' words."
"What do you mean struck dumb?" Old Man Yao, with a reddened face, indignantly responded to his son exposing the family secrets, "If it weren't for you guys being so disappointing, would your mother and I have needed to say such difficult words?"
