From Wikipedia:

The Assassin (Chinese: 刺客聶隱娘) is a 2015 wuxia film co-written and directed by Hou Hsiao-hsien. A Taiwan/China/Hong Kong co-production, the film is loosely based on the late eighth-century martial arts story "Nie Yinniang" by Pei Xing. It stars Shu Qi and Chang Chen.

The Assassin is loosely based on the late seventh-century martial arts story "Nie Yinniang" by Pei Xing, a core text in Chinese swordsmanship and wuxia fiction.The film is set in China during the Zhenyuan (貞元) reign period (785 to 805) in the middle of the Tang dynasty, a few years after the An Lushan rebellion (755 to 763). The circuit of Weibo, though nominally a part of the Tang Empire, is de facto ruled independently by military governor Tian Ji'an.
