Because of the dynasty's openness to foreign influences, and renewed exchanges with Indian culture due to the numerous travels of Chinese Buddhist monks to India, Tang dynasty Buddhist sculpture assumed a rather classical form, inspired by the Indian art of the Gupta period. During that time, the Tang capital of Chang'an (today's Xi'an) became an important center for Buddhism. From there Buddhism spread to Korea, and Japanese missions to Tang China helped it gain a foothold in Japan. Foreign influences came to be negatively perceived in China towards the end of the Tang dynasty. In the year 845, the Tang emperor Wuzong outlawed all "foreign" religions (including Christian Nestorianism, Zoroastrianism and Buddhism) in order to support the indigenous religion, Taoism. He confiscated Buddhist possessions, and forced the faith to go underground, therefore affecting the development of the religion and its arts in China. After the Tang dynasty, Buddhism continued to receive official patronage in several states during the Five Dynasties and Ten Kingdoms period, which continued under the successive Liao, Jin, Song, Yuan and Ming dynasties. This was marked by construction of new monumental Buddhist artwork at grottoes, such as the massive Buddha sculptures at the Dazu Rock Carvings in Sichuan province, as well as at temples, such as the giant esoteric statues of the Bodhisattva Guanyin in Longxing Temple and Dule Temple. The various Chinese Buddhist traditions, such as Tiantai and Huayan, experienced revivals. Chan Buddhism, in particular, rose to great prominence under the Song dynasty. Early paintings by Chan monks tended to eschew the meticulous realism of Gongbi painting in favour of vigorous, monochrome paintings, attempting to express the impact of enlightenment through their brushwork. The rise of Neo-Confucianism under Zhu Xi in the twelfth century resulted in considerable criticism of the monk-painters by the literati. Despite this, Chan ink paintings continued to be practiced by monastics through the Yuan (1271–1368) and Ming (1368–1644) dynasties well into the Qing (1636–1912) dynasty. Aside from Chan ink paintings, other forms of painting also proliferated, especially during the Ming dynasty, such as the Water and Land Ritual paintings and mural art which depict
