You really have to master the art of using chopsticks if you visit China. In every restaurant, you will be provided with chopsticks instead of forks and knives. Don't be frightened, they are easy to use. 

Use your thumb and the fourth finger to grip one stick and your forefinger and middle finger to grip and control the other stick. (See the illustration). After practising a while, you will be able to pick up pieces of food. If you are able to pick up a bean with chopsticks, this means that you have 'graduated'. If you cannot use them, you can always ask for fork and knife in a tourist restaurant.
