Public opinions[edit]

"This sentence sparked heated debate. Professional and knowledgeable elite students not abiding by the basic line of ethics makes people vigilant. A too utilitarian social environment allows us to ignore the cultivation of the most basic health personality; the indoctrination of animosity makes the restless youth narrow-minded and intolerant. From intimate roommate to poison, it's not just education that needs to rethink."[5]
