Now all of China knows you’re here is a popular quote from Mulan.
Online, it is used as a reaction image macro whenever someone reveals their presence without actually intending to do so.
The Disney animation Mulan was premiered in the United States on June 5th, 1998.
The opening scene depict a Chinese soldier lighting the signal fire on the Great Wall, after noticing the Huns.
After the warrior has lit the fire, he tells Shan-Yu, the central villain of the film “now all of China knows you’re here”.
A separate clip of the scene was uploaded to YouTube by Ed Warkentin on May 5th, 2008.
Starting in 2012, GIFs and reaction image macros would start spreading online, mostly on sites like Twitter, Reddit and Tumblr.
