Abstract: Lin Yutang was always in a state of "identity" anxiety, which was derived from the contradiction between the Christian faith of a Chinese Christian and the Chinese culture.He once called himself "pagan", and tried to return to Chinese traditional culture for the feeling of belongings.But whether Christian or traditional culture can't build up alone a spiritual home for Lin Yutang.He had to wander between oriental culture and western culture, calling himself "half oriental and half western "and "both Christian and Confucianism", so the searching for "identity" made him undertake the communicating mission of the two worlds.
