Simple yet complex Chinese work society

Humans were highly complex creatures. Some people would feel that the world was absolutely terrible and that they had no control over things around them, perhaps due to their environment or living conditions. They would think that death was also uncontrollable. However, there were also people who felt that the world was beautiful and that life and death didn't need to be controlled or worried over. Things were quite nice for them! They would only need to worry about walking their own path in life.

Everyone would experience hardships of some sort during their life. Such hardships could be passed over just by gritting one's teeth. It wouldn't be good to keep complaining. Emotions were a complex chemical or biological reaction that concretely existed. Emotions could also affect the human body's condition.
