Tug-of –war is not only popular in China, but in many other countries. Their tug-of-war match is a little different from ours. They have eight men for each team, while we may have the match between two sides with equal men or women players. Of course, they are usually tall, strong and heavy.

For a tug-of-war match, we need a long thick rope. Each team stands at one end of the rope, holding it. Then they try to pull the center of the rope, marked in the ground towards each of their own sides. The team which succeeds in pulling the center of the rope away through a certain distance is the winner.

Many foreign sports experts think we don’t have to be tall, heavy and strong to play tug-of-war. We don’t have endless energy, for a match lasts only a few minutes. The secret is good hands. The players must have big strong, hard hands. Before they start the match they put mixture of oil and petrol on their hands so they can hold the rope better.

Many foreign experts say the best hand for tug-of-war belong to the sons of farmers. This is because they have to work hard when they are still very young. Farming is a good practice for this sport!
