Taoism is based on the though of the yin and yang. It stresses on the fact that balance is found in all aspects of life around us.

Confucianism is concerned with the fundamentals and morals of building a strong society. It emphasizes on the morals of respecting the elderly, being just and fair and obeying those in charge.
