Some people compare teachers to lighthouses and students to ships. As time goes on, I think this metaphor is more and more appropriate. We are like ships crossing the ocean of life.

When the wind and waves hit, the teacher's previous education gave us a firm belief like the light of the lighthouse; When we are in the sea of Wang Yang and can't see the land of life, the teacher's previous teaching is like the flame of a lighthouse, which gives us warm hope.
