Which direction is the front, back, left and right of the fish nest?

This question is easy to answer. Fish should fish in the direction that they approach the fish nest.

For example, water flows from left to right, and fish generally come against the water, that is, from right, and the fish is on the right side of the fish nest. If the fish come from deep water at night, they will fish in front of the fish nest. If the fish are in the aquatic plants on the shore and the fish nest outside the aquatic plants, they will fish near the aquatic plants.
