We've posted a story about Hal-tank, an old Shaolin monk who is the only person in the world who can do a one-finger handstand.
Turns out, the secret is simple! Just channel all of your chi (or qi) on that finger.
A few people in the world can come close, like this guy on the right who can do a four finger handstand, but Hal-tank remains the only man who can do it with just one finger.
