Fuzhou, Fujian province, southeast China - Two university students have found a curious way to stay awake when pulling all-nighters and writing essays.
Often, students would try caffeine hits, cranking up the air-conditioning and push-up breaks, but chances are, theses ways wouldn't do the trick.
Chen Tang, 20, together with her roommate Huang Lu, 21, took inspiration from "historic scholars" to fight the urge to nap.
So, Chen remembered two legendary Chinese scholars who chose more painful methods to ensure their minds stayed alert.
One would stab himself with needles every time he started to fall asleep, while the other would tie his hair to a beam in the ceiling so that it was pulled every time he started to nod off.
Huang, who posted the pictures of Chen online, said: "Chen is so keen to succeed that she decided to give the hair trick a try, as you can see her hair is more than long enough. As we didn't have a beam in our dorm, she used the clothes dryer and claims it worked really well."
According to Chen, it helped to keep a clear mind and she plans to use it again to help focus.
"The preparation is so boring, but the hanging hair practice makes it interesting, and I really feel much more energetic by studying in this way," she said.
