Guardian (Chinese: 镇魂; pinyin: Zhèn Hún) is a 2018 Chinese web series starring Bai Yu and Zhu Yilong. An adaptation of the 2012 fantasy-danmei web novel of the same name by Priest, the series was released on the video platform Youku between June 13 and July 25, 2018. The series follows Zhao Yunlan (Bai) and Shen Wei (Zhu), a detective and a professor who investigate supernatural phenomena. Though the novel depicts their relationship as romantic in nature, the web series depicts the relationship as a platonic friendship with homoerotic subtext in response to Chinese laws prohibiting depictions of same-sex relationships on television.
