3 . Hand gestures (手势) have been commonly used in our daily communication. They add to the message by filling in what words sometimes leave behind. But are you somewhat aware of the history that goes behind some of these popular hand gestures?

◆Handshake

Whether you’re greeting someone for the first time, or successfully negotiating (商定) an agreement, shaking hands is usually the go-to gesture. Who decided on this customary gesture, anyway? The history of the handshake dates back to ancient Greece, showing that neither person was carrying a weapon.

◆Thumbs up and thumbs down

Maybe you’re familiar with the popular story of this hand gesture dating back to Roman times. When a gladiator (角斗士) lost, the crowd would either stick their thumbs out to have him killed or just not make any sign at all. The thumbs up decided the gladiator’s fate (命运) . After WWII, thumbs up only came to mean that things were going smoothly. And thumbs down meant the opposite.

◆High five

According to some sources, the high five first became popular when baseball players performed at Dodger Stadium on October 2, 1977. Glenn Burke, one of the capable players, lifted his am high above his head and slapped palms with his teammate Dusty Baker to celebrate a milestone home run, marking what is widely regarded as the first recorded example of a high five.

◆The fist bump

The fist bump comes from boxers in the 1970s after people began imitating how they touched gloves before a competition.
