The wind howls, the sky looms high; grass grows tall, wilderness stretches wide. During the Zhenguan era of the Great Tang dynasty, Nie Yinniang, daughter of General Nie Feng of the Weibo military province, and her cousin Tian Ji’an grew up as childhood sweethearts. Little did anyone expect that at the age of ten, she would be abducted by a Daoist nun. As the nun’s disciple, Yinniang trained arduously in martial arts deep in the mountains, far from human habitation. Three years passed in the blink of an eye. By then, Yinniang was as light as the wind. With swift speed, she darted to the mountaintop and, with a gentle flick of her wrist, her sword precisely pierced a hawk soaring high in the sky. Yet, faced with the chirping fledglings, she seemed unable to sever her compassion. Another two years went by. In a bamboo forest bathed in bright moonlight, master and disciple blindfolded themselves with cloth, drew their swords, and engaged in a duel. This was Yinniang’s final trial to complete her training, yet it also marked the beginning of a long and painful journey... 　　The story is adapted from a tale in Pei Xing’s "Chuanqi" (Legends) and serves as a promotional trailer for Hou Hsiao-hsien’s film "The Assassin."
