The translation of a large body of Indian Buddhist scriptures into Chinese and the inclusion of these translations together with works composed in China into a printed canon had far-reaching implications for the dissemination of Buddhism throughout the Chinese cultural sphere, including Korea, Japan, Ryukyu Islands and Vietnam. Chinese Buddhism is also marked by the interaction between Indian religions, Chinese religion, and Taoism.
Various legends tell of the presence of Buddhism in Chinese soil in very ancient times. Nonetheless, the scholarly consensus is that Buddhism first came to China in the first century CE during the Han dynasty, through missionaries from India.
Generations of scholars have debated whether Buddhist missionaries first reached Han China via the maritime or overland routes of the Silk Road. The maritime route hypothesis, favored by Liang Qichao and Paul Pelliot, proposed that Buddhism was originally practiced in southern China, the Yangtze River and Huai River region, where prince Ying of Chu (present day Jiangsu) was jointly worshipping the Yellow Emperor, Laozi, and Buddha in 65 CE. The overland route hypothesis, favored by Tang Yongtong, proposed that Buddhism disseminated through Central Asia – in particular, the Kushan Empire, which was often known in ancient Chinese sources as Da Yuezhi ("Great Yuezhi"), after the founding tribe. According to this hypothesis, Buddhism was first practiced in China in the Western Regions and the Han capital Luoyang (present day Henan), where Emperor Ming of Han established the White Horse Temple in 68 CE.
In 2004, Rong Xinjiang, a history professor at Peking University, reexamined the overland and maritime hypotheses through a multi-disciplinary review of recent discoveries and research, including the Gandhāran Buddhist Texts, and concluded:
The view that Buddhism was transmitted to China by the sea route comparatively lacks convincing and supporting materials, and some arguments are not sufficiently rigorous. Based on the existing historical texts and the archaeological iconographic materials discovered since the 1980s, particularly the first-century Buddhist manuscripts recently found in Afghanistan, the commentator believes that the most plausible theory is that Buddhism reached China from the Greater Yuezhi of northwest India and took the land route to reach Han China. After entering into China, Buddhism blended with early Daoism and Chinese traditional esoteric arts and its iconography received blind worship.
