At the banquet, Wang Bin made it clear that this time, they were specially entertained because it was their first collaboration. In the future, all transactions would take place at the market, and they would have to bring their own food. Although the two were reluctant, they didn't dare to argue.

Wang Bin knew the history of the Tang Dynasty well. During that time, the Tang Dynasty was powerful, and neighboring vassal states frequently came to pay tribute, bringing their specialties to Chang'an. To showcase the grandeur of a great nation, the Tang Dynasty would always give these tribute-bearers gifts several times the value of what they brought. This eventually led to these vassal states making frequent tribute visits.

This opened up trade routes for the Tang Dynasty, attracting more foreigners to do business in the empire. However, over time, the Tang Dynasty found it hard to handle the frequent tributes and eventually stipulated that tributes could only be made once every few years.

Wang Bin didn't want Dezha and Kun to get used to taking advantage of him, bringing a large group to freeload every time. So, it was better to set things straight from the start.
