This is a fairy tale that shows the courage and love of the dragon slayer. The master and apprentice faced the evil dragon bravely and sacrificed themselves to save others. Although the dragon is difficult to eliminate, but the will to kill the dragon has been circulating among the dragon slayer. Evil dragons can be seen as things we hate and fear, but many of these things we have to do, and there is no end to them, just like Sisyphus, who pushes boulders in the myth, every day with the hope of pushing boulders to the top of the mountain, but what we see is the result of boulders falling down again and again. Pushing boulders every day is the life of some people, but it is not the whole of life. The people and scenery we meet on the road make such a boring life vivid.
