Story of time 

When dealing with anyone, talk about interests, less or no feelings. Bosses and employees get along well because of the benefits of wages. Students and teachers get along well because of the interests of teaching, salary, and has nothing to do with personal dedication. Those who speak with money and value the interests are one thousand times stronger, ten thousand times stronger than those who speak with feelings, and ten thousand times stronger. In this world, only the interest relationship is the most fundamental, the most stable, those who advocate great love, talk about morality, talk about feelings are either bad or stupid. Everything derived from emotion will eventually be destroyed. All people are driven by money and interests to a certain extent, or they use money and interests to drive others.
