Zhang Tao's father is a physics teacher. After retirement, he reads at home every day and accumulates a lot of "completely useless but very interesting" unpopular knowledge: "The fiber in the banana peel can be made into a rope", "Elevator buttons will be more sensitive if wiped with alcohol", "It actually makes sense to close the window in summer to be cooler than opening it." My father talks to the family all day long, and everyone listens.
Zhang Tao was bored one day and took a video of his father talking about "why salt is added to the water when boiling eggs" and posted it online with the text: "My dad's retirement life." Three days later, the number of views exceeded 500,000. The comments are all: "Auntie is so cute!", "Good stuff!", "Hand in for the next issue." After reading the comments, my father pushed up his reading glasses and said, "They call me 'auntie'?"
