FOR the last 24 years Gao Yang has been practicing. He is trying to break the Guinness World Record (吉尼斯世界纪录) for most time spent sleeping on a rope. Gao ties a rope between two trees or poles (柱子), 3 meters off the ground. He stretches (伸展) out and…sleeps. Gao says that this “skill” needs “the perfect coordination (协调) of body and balancing”.
