Guardian (web series)

Guardian () 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.
The series was widely popular on the web, and received a total of 1.8 billion views by August 2018. That same month, "Guardian" was pulled from Youku amid a crackdown on "harmful and vulgar" internet content, but was later re-uploaded.
Synopsis.
"Guardian" is set on the Earth-like planet of Haixing, populated by a native human population and two alien races — the Yashou, who are able to shapeshift into plants and animals, and the Dixing, superpowered beings who live deep underground. The three races have enjoyed a peaceful co-existence since the arrival of the Yashou and Dixing over ten thousand years ago, broken only by an ancient war declared by the Dixing after a meteor strike depleted their resources. During that war, the Haixing and Yashou were led by the hero Kunlun, who became a close comrade to the Black Robe Envoy, the leader of a faction within the Dixing that sought peace. The war was won by the Haixing with the use of four holy tools crafted from the meteor. At the end of the war, Kunlun vanished, and the Black Robe Envoy became the overseer of peace between the races while awaiting Kunlun's return.
In the present, conflict has begun to erupt again between the Dixing and the surface-dwelling races. The hotheaded Zhao Yunlan leads the Special Investigation Department (SID), a group that works with the Black Robe Envoy to uphold peace and investigate cases related to the Dixing people. While investigating an incident at the local university, Zhao is assisted by Shen Wei, a biological engineering professor. The two men are drawn closer together as a mysterious enemy threatens to re-ignite war.

Removal and re-release.
On August 2, 2018, "Guardian" was pulled from Youku for "content adjustments" amid a crackdown by the National Radio and Television Administration on "harmful and vulgar" internet content.

Critical response.
Guardian has received positive reviews, with "People's Daily Online" praising the series' "progressive" storyline and "touching" drama, and "China Entertainment News" praising the story's realism and lack of sensationalism. Conversely, a review for "Yangcheng Evening News" criticized the series as "unsophisticated."
The term "Guardian girls" (镇魂女孩) was coined to describe female fans of the series. Prior to the series' removal from Youku, fans would discuss the series' homoerotic content on social media under the hashtag "socialist brotherhood" in order to avoid notice from state censors.
