A little joke about the Eight Immortals

In other words, among the Eight Immortals in the ancient celestial world, everyone had an apprentice, except Lv Dongbin. The Seven Immortals are served by disciples every day. Lv Dongbin was very unhappy, so one day he decided to take an apprentice. But it is not so easy to be his apprentice. To become Lv Dongbin's apprentice, there must be one condition, that is, "not greedy"! So Lv Dongbin left heaven and came to earth to find a suitable person. Lv Dongbin disguised himself as a businessman selling oranges and set up a stall to sell oranges in the market. The price tag was "two pence, ten pence". Any greedy person will buy two pence, so many people will buy two pence. As the days passed, Lv Dongbin still couldn't find the right person, and he gradually became disappointed. Suddenly one day, a young man came and bought only a penny. Lv Dongbin immediately.

My eyes lit up and I thought: I finally waited for today. This man is really amazing! I rekindled a burst of hope in my heart, and I got it for nothing! Great! "Just after the young man paid the money, he took the orange and turned away. ㄟ, Lv Dongbin stopped him and said, Wait a minute, young man. Why didn't you buy a penny of oranges just now? "The young man replied," ㄎㄢ'! ! I only have a penny. Of course, I only buy oranges for a penny. If I had two pence, I would spend two pence on oranges. "Then I turned and left.
