cheating is a one of the topics in a video which I saw in class. In the video, cheating of teacher and Sumou which is a Japanese traditional sports were treated. I did not think that cheating was being done in the school and Sumo world. School is the place where we are taught the right things. Although it is for raising the evaluation of the schools, cheating is not forgiven. This is neither for the teachers nor for the students. Being done cheating in Sumou world is a very surprising fact. This is because I thought that Sumou is sacred and innocent sports. Deciding the outcome intentionally is called Yaocho in Japan. Yaocho is also what is not forgiven. If the player you support does Yaocho, you will feel sad and angry. To prevent such cheatings, we should crack down strictly it. For example, if athlete who does cheating is forced to quit this sports, such humble people will be decline. Cheating is bad things. A serious person should not lose because of cheating. I hope that all people do not cheat, and it is become a fair world.
