Taking into account the Sino-foreign ideological interactions, this book makes a vivid tour to the Chinese development of religions for several thousand years. In a reasonably objective language, it systematically reviews Chinese religious traditions, precisely summarizes the fundamental feature of Chinese ancient religions and their mutual relationships as ""a diversified harmony"", which is specifically interpreted as ""honoring the heaven and ancestors, pursuing harmony of diverse sources, prioritizing politics with the support of religions, and valuing virtues in favor of worldly affairs"". The book straightens up the history and status quo of Christianity and Islam as well as of the Chinese-foreign religious exchanges, tells the religious development in Tibet, Xinjiang, Hong Kong, Macao and Taiwan, and provides insight into the world's relevant hot issues such as the religious extremism, terrorism and heresy. This book interprets the ""harmony"" of Confucianism, Buddhism and Taoism in traditional Chinese culture. In both theoretical and practical veins, it answers why the Communist Party of China, an atheistic Party, can sincerely adopt the policy of freedom in religious belief, unite the believers and non-believers to the largest extent into the cause of reform and opening-up and socialist modernization drive, so as to contribute to the realization of the China Dream of national renewal.
