As for how the shrimp were obtained, it was, of course, the result of negotiations between Jiang Chuan and Su Zhen.
Jiang Chuan was a businessman, and he was adept at the process of buying on credit.
He told Su Zhen that he had only fifty coins on him. He promised to pay the remaining twenty yuan after selling the fish the next morning, and would also pay an extra five coins as interest for the credit.
Su Zhen, being a businessman himself, wouldn't miss out on a good deal, so he readily agreed.
After distributing the food, Su Zhen also had plans to go to town. They agreed to meet the next day at noon at the only restaurant in town for the deal. Since Su Zhen received extra money, he was willing to let Jiang Chuan take all the shrimp.
