Taoist ethics is primarily linked with longevity. Since everyone is eager for longevity, Taoism takes this as a tool to bring up many requests to people. In fact, this is where Taoism is in common with other religions in attaining their goals through cherishing ideals, just like Elysium in Buddhism and Heaven in Christianity, etc.
As Taoism preaches, one must nicely obey the social ethics for the purpose of longevity. Everybody must accumulate good virtues, do good deeds and obey various kinds of social norms. In all kinds of classic scriptures, Taoism emphasizes that in addition to keeping away from bad deeds and helping others, one must also be loyal to his country, show respect to his parents, and avoid the selfishness of human nature. Meanwhile, Taoism also warns that one will suffer from a reduced life span or an early death once he commits evil.
Such kind of Taoist thought is the authentic Chinese ethics. In terms of the effect, to some extent Taoist theories have a positive influence on Chinese society.
