The manager, a cautious man who was not prone to ridicule, said to Li Du, "If you pick your watermelons, you have to choose ten and arrange them in order of ripeness!"
Li Du laughed and said, "Didn't you just say all your watermelons have similar ripeness? How can there be ten grades?"
"Yes, do you know what the ten levels of ripeness stand for? Do you have raw melons here?" A Chinese girl put in.
The manager was flustered. "Of course we don't have raw melons, but there are still some subtle differences…"
Li Du shook his head and said, "Ten is too much. How about this, let's make it seven. I pick out seven watermelons and rank them in order of ripeness."
The manager thought about it and said, "Okay, seven, it's a deal."
Li Du smiled. "No problem. I'll let you see our Chinese ability to evaluate watermelons by tapping them."
"Bad luck for the fool," Brother Wolf said, shaking his head.
