    When mentioning China, what comes to mind? As a country with a history of more than 5000 years, China is rich in civilization and culture. What best represents China?

Confucius (551BC - 479 BC)

    Confucius was a teacher and philosopher from the Spring and Autumn Period of Chinese history. The philosophy of Confucius stresses individual morality including kindness, fairness, politeness, and sincerity. Confucius' principles have a broad basis in common Chinese tradition and belief.

Dragon

    A dragon is a legendary creature, typically with winding or crawling characters. The dragon symbol is frequently used on ancient Chinese emperor's items including chairs or costumes. It is considered a representation of power.

Peking Opera

    Peking Opera is considered the essence of China. As the larger form of Chinese opera, it has many “firsts” in Chinese dramas: the abundance of talents, the number of artists, opera groups and audience.

The Great Wall

    There is an old saying that goes, “He who has never been to the Great Wall is not a true man.” The Great Wall, one of the greatest wonders of the world, is a destination one must see when visiting China.

Traditional Chinese Medicine (TCM)

    Developed in China, TCM has a tradition dating back to more than 2,000 years, including various forms of herbal medicine, cupping, massage, exercise (Qigong), and dietary therapy.

    An Indian movie about two sisters has become a huge hit in China. The Hindi language film, called Dangal, has earned almost $170 million in China since its release there on May 5.

    Much has been written about why Dangal has enjoyed such big success in China. Some people say one reason is that the film's star and producer, Aamir Khan. He is famous in India's Bollywood film industry. Two of his earlier films were also big hits in China.

    Khan's popularity was clear after he got more than 600,000 followers on the Chinese social media service Sina Weibo within two months of joining. But he is not the only reason that the film strongly connects with audience across China. Media has pointed out how it shows similarities between parental systems in China and India.

Dangal is based on the true story of a man who enjoyed the sport of wrestling(摔跤). He competed as a wrestler, but never could achieve his lifelong dream: winning a gold medal. As a father, he wanted his son to win the medal. But his wife only gives birth to daughters. So he finally decides to train them to be world-class wrestlers.

    The movie is more serious than most Bollywood productions, which tell happy love stories and include colorful music and dance performances.

    Edward Chan is a professor at the Hong Kong Polytechnic University. He says the strict way of parenting in the film is something people in China can easily relate to. "I think the father role described by the movie in India is quite to the culture, especially the traditional culture in China."

    The Chinese government supported Global Times newspaper pointed that movie critics (评论家) in China did not like Dangal. Most of them agree with the fact that the father in the film was forceful in pushing his daughters to become wrestlers. But the film Dangal is really aimed to educate children to work for their dreams.

    With at least a dozen wildfires going through western North Carolina in the fall of 2016, it would take more than one local fire department to fight the flames. In early November, the federal government sent over a team of firefighters from the Interagency Hotshot Crews.

    Most of the Hotshots stayed at Hinton Rural Life Center in Hayesville, North Carolina. The center reached out to the media and community groups, hoping to get four volunteers per day to help things run smoothly for their firefighting guests. They didn't expect a response quite so unbelievable.

    Within two days, over 200 people—about a third of the town's population—reached out to offer help, according to the center's website. Meals and accommodation were already being taken care of, so they went above and beyond the basic things. Community members donated over 1,000 goods, including sports drinks, snacks, eye drops and so on.

    Even the kids in Hayesville participated, sending thank-you cards, pictures and signs to motivate the Hotshots. The team received over 2,000 thank-you notes. After the fires were put out and the firefighters were preparing to go home, the town threw a parade（游行）to thank them and wish them well.

    The firefighters were at a loss by the generosity from Hayesville. They put together their own thank-you in a YouTube video.

    “You guys don't know how much you mean, all the support you guys give us, '' says Ron, a firefighter from Oregon, in the video. “Out of four years when I've been fighting fire, this is about the most hospitable（好客的）state and county I've ever been in. And it brings tears to my eyes just thinking about it.”

    Technology offers conveniences such as opening the garage door from your car or changing the television station without touching the TV.

    Now one American company is offering its employees a new convenience: a microchip implanted (植入) in their hands. Employees who have these chips can do all kinds of things just by waving their hands. Three Square Market is offering to implant microchips in all of their employees for free. Each chip costs $300 and Three Square Market will pay for the chip. Employees can volunteer to have the chips implanted in their hands. About 50 out of 80 employees have chosen to do so. The president of the company, his wife and their children are also getting chips implanted in their hands.

    The chip is about the size of a grain of rice. Implanting the chip only takes about a second and is said to hurt only very briefly. The chips go under the skin between the thumb and forefinger. With a chip in the hand, a person can enter the office building, buy food, sign into computers and more, simply by waving that hand near a scanner. The chips will be also used to identify employees. Employees who want convenience, but do not want to have a microchip implanted under their skin, can wear a wristband (腕带) or a ring with a chip instead. They can perform the same tasks with a wave of their hands as if they had an implanted chip.

    Three Square Market is the first company in the United States to offer to implant chips in its employees. Epicenter, a company in Sweden, has been implanting chips in its employees for a while.

    Three Square Market says the chip cannot track the employees. The company says scanners can read the chips only when they are within a few inches of them. “The chips protect against identity theft, similar, to credit cards.” The U.S. Food and Drug Administration approved the chips back in 2004, so they should be safe for humans, according to the company.

    In the future, people with the chips may be able to do more with them, even outside the office. Todd Westby is Chief Executive Officer of Three Square Market. He says, “Eventually, this technology will become standardized allowing you to use this as your passport, public transit, all purchasing opportunities, etc.”

    Scientists recently discovered that pictures on cave walls at Creswell Crags are the oldest known in Great Britain. But they didn't find out in the usual way.

    Archaeologists often date cave art with a process called radiocarbon dating. The technique can measure the age of carbon found in charcoal (木炭) drawings or painted pictures. Carbon is an element found in many things, including charcoal and even people. But in this case, there was no paint or charcoal to test. People carved the pictures of animals and figures into the rock using stone tools. The scientists had an "aha!" moment when they noticed small rocks stuck to the top of the drawings. The small rocks must have formed after the drawings were made.

    "It is rare to be able to scientifically date rock art," said Alistair Pike, an archaeological scientist at Britain's University of Bristol. "We were very fortunate that some of the engravings were covered by stalagmites(石笋).

    When a test proved that the stalagmites formed 12,800 years ago, the scientists knew the art underneath them had to be at least that old. And some of the animals shown, like the European bison, are now extinct-another tip-off that the art is quite old.

    The artists came to Creswell Crags, This place is one of the farthest points north reached by our ancient ancestors during the Ice Age. At that time, much of the North Sea was dry, so people could move about more easily.

    Some tools and bones found there are 13,000 to 15,000 years old. They show that the travelers hunted horses, reindeer, and arctic hare. Their artwork is similar to art in France and Germany. It tells scientists that the Creswell Crags artists must have had a close connection to peoples several thousand kilometers away—another important clue to understanding how humans spread out across the world.
