What are the outstanding painters in ancient China? What are their masterpieces or styles?

China painting has a long history and fine traditions. From ancient times to the Warring States period, silk paintings, portrait bricks and stone in the Han Dynasty have reached a high level. Since Wei, Jin, Southern and Northern Dynasties, many famous painters and schools have emerged, with their own distinctive artistic characteristics and styles. During the Wei, Jin and Six Dynasties, there appeared "three outstanding figures in the Six Dynasties" including Gu Kaizhi in the Eastern Jin Dynasty. China's painting reached its peak in the Tang and Song Dynasties. Besides the original figure painting, landscape painting and flower-and-bird painting all became independent painting subjects. As figure painters, Wu Daozi, who was honored as a "painting saint" by later generations, and Yan Liben, who was good at historical painting and portrait painting, emerged. Landscape painters have formed different styles and schools. For example, in the Tang Dynasty, Li Sixun was good at green landscapes, and Wang Wei was good at ink landscapes; Jing Hao and Guan Tong in the Five Dynasties are northern landscape painting schools which mainly depict the real scene of the Central Plains. Dong Yuan and Ju Ran are southern landscape painting schools which mainly describe the scenery characteristics in the south of the Yangtze River. Li Cheng and Fan Kuanduo in the Northern Song Dynasty painted magnificent northern landscapes, while Ma Yuan and Xia Xuan in the Southern Song Dynasty pursued painting half a mountain or a corner of water with fewer wins. During the Tang and Song Dynasties, Cao Ba and Han Gan, who were good at painting horses, Dai Song, who was good at painting cows, Huang Quan and Xu Xi, who were good at painting flowers and birds, and "literati paintings" represented by Wen Tong, Su Shi and Mi Fei, and so on. The Yuan, Ming and Qing Dynasties are the times when China's painting art links the past with the future. The "Four Masters of Yuan Dynasty" refer to Huang Gongwang, Zhen Wu, Wang Meng, Ni Zan and others, who have played an important role in the development of traditional ink and wash landscape painting. The "Four Masters of Ming Dynasty", also known as the "Four Masters of Wumen", refers to the painters Shen Zhou, Wen Zhiming, Tang Yin and Chou Ying who engaged in painting activities in Suzhou in the middle of Ming Dynasty, and led them to form the most influential painting school in Ming Dynasty. "Eight Eccentrics in Yangzhou" is the general name of eight innovative painters with similar styles who were active in Yangzhou, Jiangsu Province during the reign of Emperor Qianlong of Qing Dynasty. Their common feature is to emphasize individual expression.
