Most people around the world are right-handed. This also seems to be true in history. In 1799, scientists studied works of art made at different times from 1,500 B.C. to the 1950s. Most of the people shown in these works are right-handed, so the scientists guessed that right-handedness has always been common through history. Today, only about 10% to 15% of the world's population is left-handed.

Why are there more right-handed people than left-handed ones? Scientists now know that a person's two hands each have their own jobs. For most people, the left hand is used to find things or hold things. The right hand is used to work with things. This is because of the different work of the two sides of the brain. The right side of the brain, which makes a person's hands and eyes work together, controls the left hand. The left side of the brain, which controls the right hand, is the centre for thinking and doing problems. These findings show that more artists should be left-handed, and studies have found that left-handedness is twice as common among artists as among people in other jobs.

No one really knows what makes a person become right-handed instead of left-handed. Scientists have found that almost 40% of the people become left-handed because their main brain is damaged when they are born. However, this doesn't happen to everyone, so scientists guess there must be another reason why people become left-handed. One idea is that people usually get right-handed from their parents. If a person does not receive the gene (基因) for right-handedness, he / she may become either right-handed or left-handed according to the chance and the people they work or live with.

Though right-handedness is more common than left-handedness, people no longer think left-handed people are strange or unusual. A long time ago, left-handed children were made to use their right hands like other children, but today they don't have to.

Has your mother or grandmother ever made embroidered (刺绣的)clothes for you? In the past, Chinese people often embroidered on hats, shoes and dresses. Some girls would even embroider on a sachet (香囊)as a gift for their lovers.

Shu embroidery comes from Sichuan. It is said that Shu embroidery is the old lest kind of embroidery in China. People began to make it during the Han Dynasty (206BC-220AD).They sold it to other countries such as ancient Rome.

Shu embroidery takes time. It might take as long as a whole day to finish just 10 cm. Embroidery workers need to divide each silk thread (丝线) into more than 10 or over 30 smaller threads. Each smaller thread is thinner than a human hair.

Meng Dezhi, who used to work at the Chengdu Shu Embroidery Factory，has been making Shu embroidery for over 40 years. She loves this form of art and wants more people to try it, so she gives lessons in universities. She said. "Although the work is hard, Shu embroidery stands for thousands of years of Sichuan culture. It is a symbol of Chinese culture as well."

Hi, everybody. Here we're in front of the South Gate. Go straight on, and you'll find the Panda House. Pandas are cute. They like to eat bamboo and lie down all day long. Every year, lots of visitors come here to see them. 

Walk along the road. To the north of the Panda House, you'll find the lions. Lions are the kings of the animal world. Remember that they're dangerous. Never go near them. 

Turn left, and to the west of the Lions' Area, you'll find the World of Birds. Birds make beautiful sounds when they sing. To the north of the World of Birds is the Monkeys' Forest. Monkeys are clever and funny. They jump around and make people laugh. 

Then turn right, and to the east of the Monkeys' Forest, you'll see the giraffes(长颈鹿). They're quite tall. Their long necks help them eat the leaves from trees. 

Northeast of the giraffes there's a bridge. Cross the bridge, and you'll see the elephants. Their large ears are like open fans. 

Here you can see all kinds of animals. Have a nice trip!
