Input: Consider Input: Article: It was originally built to defend an empire ,but now parts of the Great Wall of China are crumbling so badly they need someone to hurry to their defense. About 2,000 kilometers, or 30%,of the ancient fortification built in the Ming Dynasty has disappeared due to natural and human damage, according to the Beijing Times. And the situation could worsen, experts are warning as not enough is being done to preserve what remains. "It's a great pity to witness the Great Wall in such terrible situation ," Mei Jingtian, a volunteer who has worked for three decades to safeguard the structure and has founded the Great Wall Protection Association, tells CNN. About 8,000 kilometers of the structure dates from the Ming period between the 14th and 17th centuries and is considered by some to be the original Great Wall.Of this, 2,000 kilometers is made up of naturally occurring earthworks - and so only 6,000 kilometers of actual Ming dynasty wall was ever built. Stretches built in other eras make up a total length estimated up to 21,000 kilometers. Many visitors to china associate the Great Wall with a widely restored stretch of Ming era wall at Badaling near Beijing, but this is far from typical of most of the structure. According to a 2014 survey done by the Great Wall of China Society, only about 8.2% of the Great Wall is in good condition, with74. 1% classified as poorly preserved, "The Great Wall is a vast heritage site - over 20,000 kilometers - thus increasing the difficulty in preservation and restoration," Dong Yaohui, deputy director of the Great Wall of China Society, tells CNN. "Reliance on a very small amount of manpower by the local heritage departments is not enough to guard and protect the site." A recent increase in interest from tourists in visiting wild sections, known as the "Wild Great Wall," has Accelerated its deterioration ,according to the report.

Input: Consider Input: Article: Most people call it "body language" -- the clues to the meaning that we get from gesture, facial expressions, posture -- everything that isn't spoken.Experts call it "nonverbal communication," but it means the same thing: a second source of human communication that is often more reliable to understanding what is really going on than the words themselves. Understanding body language is important to success, whether in the business world or in our personal lives.However, most of our ideas about body language are wrong, according to modern communication research. There is a belief that people with shifty eyes are probably lying.As Paul Ekman says, "When we asked people how they could tell if someone was lying, too much blinking and shifty eyes were the winners.But sometimes people act like that because they are shy.Liars pretend to be calm in order not to be caught. Ekman goes on to argue against such a wrong belief.Although this kind of body language is probably an expression of nervousness, it is not always because the person is lying.Shyness can, for example, make people shift their eyes.To understand what someone's behavior means, you have to watch them carefully. There is also a belief that when meeting someone, the more eye contact , the better.As a result people would like to make initial contact in formal situations, like a job interview, by staring fixedly at the other human.Yet Ekman points out that most of us are comfortable with eye contact lasting a few seconds, but any eye contact that is longer than that can make us nervous. In short, you must carefully consider the speaker and the speaking environment.Experts suggest that unless you know about someone's basic communication style, you will have little hope in understanding their true feelings through body language.In other words, body language carries important but not always true messages.
