It can be said that without religious belief, there is no national culture.
National culture was originally evolved from religious culture. The culture of any nation is deeply branded with religion.
It is religious belief that creates splendid national culture.
Faith means believing, respecting and admiring.
Because of faith, people love it; Because of love, people explore; Because of exploration, people think; Because of thinking, we enrich our thoughts and enhance our realm; Rich ideas and lofty realms are naturally revealed and condensed into culture.
China culture is like this (Confucianism, Buddhism and Taoism), and so is western culture (God Christ).
Not only culture, but anything in the world will be difficult to succeed without firm belief.
