Xiang Wan has three major hobbies in life: eating sweet and sour pork ribs, collecting Shuihu cards, and taking pocket money from Chi Huai's pocket. The first two items are sometimes out of stock, but the last item is never in short supply - because Chi Huai always ranks first in the exam, and his mother always gives him the full amount of money. For sixteen years, she stepped on the same brick outside his courtyard wall, used the same copper key, and took the same ten-dollar note from his pocket. Until one day Chi Huai sewed the pocket shut. Xiang Wan became anxious and chased him all over the corridor: "Chi Huai, what do you mean?!" "Xiang Wan," he turned around, the tips of his ears were red, "if you take it again, I will let you take responsibility."
