The screamer starts with some Chinese text on a white background, warning viewers not to open media of unknown origin as it might contain screamers. However, after 6 seconds, the image switches to a frightening woman staring at the viewer for 2 seconds, then the GIF repeats itself. Since it is an animated image, there is no accompanying sound, and therefore, no scream.
The full text reads: "Do not click on videos in QZone unprepared, especially those only several seconds in length. There is a high probability that they will pop out a ghost with scream. Also you should be aware of those GIFs and long pictures of chat history as they might contain the same prank. Being shocked at midnight, not only you may not hold your cellphone steadily enough to not drop it, but also even have a heart attack to death. What's more, these idiots who have been scared by these things and decided to spread them to their contacts are also stupid. You'd better go to bed early, as staying up late harms your health too."
