The place they wanted to fish was actually the area where Murong Yun and Hua Le came by boat during the day.
A little further to that water area, there is an area that was specially circled by a net by the people in the village, and some fast-growing fry were placed in it, just to get more fish to eat.
Originally, the fat fish in the village were only allowed to be eaten during the Chinese New Year every year. Because the village had a large population, everyone could not get too much of it.
