What did the wangaran do during silent bartering?

During silent bartering, the Wangaran people engaged in trade without direct communication, using a system of placing goods in designated areas to indicate their offerings. They would leave their items, such as gold or salt, at a specified location and then withdraw to a distance to await the responses from potential traders. If the other party found the goods acceptable, they would leave their own items in exchange. This method allowed for trade to occur without the need for spoken negotiation or face-to-face interaction.
