Observation and Inference

There were some mobile stalls along the riverside that sold drinks. It could hint to pass stalls that sold cooked food and refreshments along the river and the mobile stalls could be remnants of the businesses along the river. There were boats that carried people across the river. It could also tell us that there were ferry services on the river and the ferries are likely modern boats that are licensed to cruise on the river. Most likely, there were also traders on the river, as hinted by the pictures displayed around the area that showed the sampans on the river, with goods such as fabric and spices.
