Look up the dictionary joke to eat Yuanxiao.

Once upon a time, Confucius once took two errands to travel. One day, three people were hungry and found a store. When they came closer, there was a sign that said, "Authentic sweet-scented osmanthus dumplings are one penny". Confucius rummaged through his pockets and found that there was only one penny. In desperation, let the students take out their pens and add a vertical to the word "one", which becomes "ten cents". Then the master and the apprentice went into the store and asked for ten jiaozi. Confucius and other three people finished eating, took out a penny and gave it to the boss. They turned around and went in, and the boss quickly went out to ask for money. Confucius pointed to the sign and said, "clearly mark the price, and you get what you pay for!" " . The boss was speechless. When Confucius left, he patted the boss on the shoulder and said with a smile, "I'd better be polite to you today, otherwise, I'll have to add another one to it and turn it into" authentic sweet-scented osmanthus dumplings, and you get what you pay for! " "。
