    Shadow puppets（皮影）are made of hard leather（皮）. The leather is cut out in the shape of a person, an animal or an object. Each puppet is painted in bright colours and put on a stick. Some puppets have movable（可移动的）arms and legs.

During a shadow puppet play, the performers stand behind a white screen with lights behind it. The audience sit in front of the screen. The performers hold the puppets very close to the screen so the audience can see the puppets' shadows clearly. Then they move the puppets around and do the voices of the different characters.

Shadow puppet plays are an ancient Chinese art. Now with TV and films, shadow puppet plays are not as popular as before. But to keep the traditional art form alive, some performers still play it even though they made a little money.

A Chinese knot（结）is usually made of a thin rope. It can be in the shape of an animal, a flower or a Chinese character with a special meaning. Red ropes are usually used because red is a lucky colour for Chinese people.

Many Chinese knots have special meanings. People think that these knots can bring them happiness or good luck, so they carry the knots with them or put them up at home.
