Since the time of emperor Robben in the Tang Dynasty (635 years), Christianity has had a history of nearly 1400 years in China. The Protestantism has been developing for more than 200 years since Morrison came to China in 1807. After the reform and opening up, with the implementation of the religious policy and the social and economic development, the Chinese Christianity has not only recovered rapidly, but also has brought in the remarkable development, which has become the common concern of the domestic cultural, ideological, academic and political circles.
