If you don’t quite fit in among the morning people or night owls（猫头鹰）, well, you might soon have your own sleep type. Now, researchers add two more types; the afternoon people and the nappers（睡午觉的人）.

A group of researchers in Belgium did a short online survey to over 1,300 people, aged 12 to 90, asking them questions about their sleep habits and tiredness levels throughout the day. They found that there were 631 people who fit into one of the two well-known night and morning types. Morning people are wide awake in the morning and sleepier as the day progresses. Owls are just the opposite.

But they also found, based on the wakefulness-sleepiness answers, that there were 550 people that fell into one of two other groups, the nappers and the afternoon people.

Of all the types, afternoon people wake up the sleepiest and then they become active around 11 a.m., staying that way until about 5 p.m., after which they get tired again. The “nappers” wake up active and stay active until about 11 a.m., after which they get really tired until about 3 p.m. After 3 p.m. until about 10 p.m., they are active again.

It is also found that the results, for the most part, held true in men and women, in both day-and-night shift workers and in all ages. There were some small differences in age, such as older people are more likely to fall more into the “nappers” group.

Now what type do you belong to?

Traditional clothing plays an important role in any country’s history and culture. In China, when it comes to traditional clothing, Hanfu, Qipao and the Chinese tunic suit（中山装） are the most popular. However, most Chinese people are unclear about them. Here is some information about these three kinds of clothing.

Traditional Hanfu

Hanfu was created for Han people in the beginning. It shows the Chinese belief（信念）. Its color, its style and even the length all relate to Chinese culture.

Hanfu first appeared in the Shang Dynasty, over 3, 000 years ago. It was popular for a long time in Chinese history from the Qin Dynasty to the Ming Dynasty. At the beginning of the Qing Dynasty, however, it lost its popularity. In recent years, with   growing calls for reviving（复兴） traditional Chinese culture, many Chinese people have taken a liking to hanfu.

Qipao

Qipao, also known as the Cheongsam（旗袍）, appeared in the 1920s and remained as the “national clothing” until the 1950s. At first, people made it wide and loose（宽松的）, covering most parts of the body. Yet it was not beautiful and people wanted a more beautiful kind of clothing. So in the 1930s, people made the traditional Qipao tight（紧的） to show the beauty of a woman’s body. Now, lots of women still like to wear it.

The Chinese tunic suit

It is also called the “Sun Yat-sen suit”, because it was named after Sun Yat-sen, a famous person in chinese history. It looked simple but good, so it quickly became popular among Chinese   men in the mid-20th century. Although other kinds of clothing have replaced it, leaders of China still wear it when going to important events.

When Chen Lihui, the performer of Fujian Puppetry(木偶表演艺术), controlled a puppet to move his body,     46    (near) 200 kids in the room laughed together.

Chen performed the wonderful     47    (tradition) art to the students and teachers of Paint Branch Elementary School in Maryland, the US on Wednesday.

The headmaster of the school said, “He tells his stories     48     arts and movements. It’s the first time that we saw such     49     interesting Chinese puppet show. We were so amazed at it and kept     50    (say) wow, wow, wow!”

Chen said, “In the past, when the     51    (perform) was over, I left quickly.

People didn’t know me and I didn’t know them,     52    . This time, I was able to interact (互动) with so many people and experience real American life. It feels so different.”

After the show, Chen     53    (invite) a few students to have a try. He also offered     54    (they) a lot of different puppets. The headmaster said, “Everyone would like to have had him for a much     55    (long) time. Everyone has realized that in this age of technology, this is a wonderful way to enjoy and learn in life.”
