When the Chinese began to use chopsticks as an eating instrument is anybody's guess. They were first mentioned in writing in Liji (The Book of rites), a work compiled some 2,000 years ago, but certainly they had their initial form in the twigs which the primitive Chinese must have used to pick up a roast after they began to use fire. The twigs then evolved into the wooden, tapering sticks as we know them today.
Chopsticks may be made of any of several materials: bamboo, wood, gold, siler, ivory, pewter, and plastics. In cross-section, they may be either round or square. Some of them are engraved with coloured pictures or calligraphy for decoration. Ordinary chopsticks used in Chinese homes are of wood or bamboo, those for banquets are often ivory, whereas gold ones belonged only to the royalty and aristocracy.
The correct way to use chopsticks is to hold the pair in the hollow between the thumb and forefinger of your fork hand. The one closest to your body should rest on the first joint of the ring finger and stay relatively immobile. Hold the other one with the forefinger and middle finger, which manipulate it like pincers to pick up the food. The strength applied by the fingers should vary with the things to be taken hold of. The skill to pick up, with speed and dexterity, small things like beans and peanuts and slippery things like slices of preserved eggs can only come from practice and coordinated action of the fingers.
Incidentally, using chopsticks has a great deal in common with wielding a brush to write Chinese characters. Those who write a good hand, some scholars have observed, are invariably
those who handle the chopsticks correctly. One holds the writing brush basically in the same way as one would the moving chopsticks and, while writing, one must achieve a coordination
in the movement of the shoulder, arm, wrist and fingers in order to write well.
Westerners are often impressed with the cleverness of the Chinese hand that makes embroideries and clay sculptures with such consummate skill. Could not this also be attributed, at least partly, to the constant use of chopsticks?
