This is when a shocked zoo monkey fell off a window edge at the sight of a woman gazing through the glass.
The video shows Ms Liu from Changchun in north-eastern Chinese Province of Jilin visiting her local Zoo.
Ms Liu stated that she had only seen monkeys on television and was excited to see one live.
The viral video shows the monkey with its back to her, perched on a window edge.
Ms Liu moves closer to the glass and taps it in the hope it will notice her.
It is so shocked to see her that it falls off the ledge.
The footage ends with the woman exclaiming and laughing, then covering her face with her hands.

Ms Liu claimed that it was her first experience with a monkey in person.
Later, Ms Liu joked on social media that the monkey had reacted this way to seeing the young lady with no makeup.
Ms Liu uploaded the footage to Douyin, a social network in China that is TikTok. It has been widely reshared by netizens.
The clip was captioned by her: “I still can’t understand why this monkey saw my this way, or because I wasn’t wearing make-up?”
Footage of the stunned monkey was captured following a viral video, also on Douyin, of a gorilla biting at zoogoers on 16 October in Zhejiang, an eastern Chinese province.
