Why does everyone in China carry this small gourd? Here's why.

The gourd sounds like "fortune" in Chinese—Americans call it the "vacuum gourd." Hang it by your bed to suck away nightmares; put it in your office to calm your boss's temper. Carry a tiny one during flu season—you'll dodge every sneeze from coworkers.It can be used as a keychain, a phone charm, or hung behind the front door at home, which is also great.
