(m)\n\nThe Great Wall of China, also known in China as the Great Wall of 10,000, is an ancient Chinese fortification built from the end of the 14th century until the beginning of the 17th century, during the Ming Dynasty, in order to protect China from raids by the Mongols and Turkic tribes. It was preceded by several walls built since the 3rd century BC against the raids of nomadic tribes coming from areas now in modern day Mongolia and Manchuria.The Wall stretches over a formidable 6,350 km (3,946 miles), from Shanhai Pass on the Bohai Gulf in the east, at the limit between China proper and Manchuria, to Lop Nur in the southeastern portion of Xinjiang Uygur Autonomous Region. \n\nThe first major wall was built during the reign of the First Emperor, the main emperor of the short-lived Qin dynasty. This wall was not constructed as a single endeavor, but rather was created by the joining of several regional walls built by the Warring States. It was located much further north than the current Great Wall, and very little remains of it. A defensive wall on the northern border was built and maintained by several dynasties at different times in Chinese history. The Great Wall that can still be seen today was built during the Ming Dynasty, on a much larger scale and with longer lasting materials (solid stone used for the sides and the top of the Wall) than any wall that had been built before. The primary purpose of the wall was not to keep out people, who could scale the wall, but to insure that semi-nomadic people on the outside of the wall could not cross with their horses or return easily with stolen property.

well, if we look at some of the other walls that have been built, the Great Wall of China for instance, we can see it from space now that we are above it. To the other wall, as in Berlin, we already took that one down.

I don't neccessarily know about strongest, but there are actively building their military at an incredible rate. What is most alarming is that they seem to only be focusing on improving their offensive potential. China has no real security threats in Asia to defend against, so peolple should ask themselves, why an offensive build up?

China is pretty smart... I think we can all agree they have an artifically devalued currecy, which gives them a nice advantage in the world market, but hey it's not like the U.S. doesn't have some nice advatages too. I worry a lot about human rights issues there and I wish they could maybe set a little better example for Southeast Asia. But as for it's role in the international community, it's a billion people, huge workforce for potentially cheap labor and huge market for imported goods. The needs are pushing up the prices for goods internationally though, like oil, but hey that's consumerism.

China is an ILliberal capitalist country.  They are communist in name only, probably because they'd find it too embarrassing to admit that they've totally abandoned communism and did so years ago.  But they did nto abandon their autocratic control-freak government.

Because China is an oppressive communist country. They sensore everything their people see, they don't want any individuality or new ideas. China is a country that forces the people to believe what they want them to believe.

China has had double digit GDP growth for the past 20 years (in comparison, developed countries have GD growth of about 2.5 - 3.5 %. India is growing at a very fast pace as well, with its continued dominance in IT. However, China gets approximately 10 times the amount of foreign investment as compared to India. \n\nThere is no doubt that these countries are growing: the question is whether these countries are stable politically in the long term.

An Asian police state?  No, China's government is in a state of flux.  Right now,  China's society seems to be stratified; there isn't much middle ground between the haves and the have nots.  The government is designed to provide for the have nots, but the power of big businesses (from outside investment) is something the government currently can't check.  In time, the government will obtain the resources to correct this imbalance.  China has no intention of subjugating its people, if that's what you mean.

The Wall is included in lists of the "Seven Medieval Wonders of the World" but was of course not one of the classical Seven Wonders of the World recognized by the ancient Greeks.\n\nThe Wall was made a UNESCO World Heritage Site in 1987.\nThe Great Wall of China as seen in a false-color radar image from the Space Shuttle, taken in April 1994\nEnlarge\nThe Great Wall of China as seen in a false-color radar image from the Space Shuttle, taken in April 1994\n\nMao Zedong had a saying, 不到长城非好汉 bú dào Chángchéng fēi hǎo hàn, roughly meaning "you're not a real man if you haven't climbed the Great Wall".\n[edit]\n\nFrom outer space\n\nThere is a long standing disagreement about how visible the wall is from space.\n\nRichard Halliburton's 1938 book Second Book of Marvels said the Great Wall is the only man-made object visible from the moon, and a "Ripley's Believe It or Not" cartoon from the same decade makes a similar claim. This popular belief has persisted, assuming urban legend status, sometimes even entering school textbooks. Arthur Waldron, author of the single most authoritative history of the Great Wall written in any language, has speculated that the belief about the Great Wall's visibility from outer space might go all the way back to the fascination with the "canals" some people during the late nineteenth century believed to exist on Mars (The logic was strange and simple: If Earthlings can see the Martians' canals, the Martians might be able to see the Great Wall). But in fact, the Great Wall simply cannot be seen by the unaided eye from the distance of the moon, much less that of Mars.\n\nThe distance from Earth to the moon is about a thousand times greater than the distance from the earth to a spacecraft in near-earth orbit. If the Great Wall were visible from the moon, it would be easy to see from near-earth orbit. In fact, from near-Earth orbit, it is barely visible, and only under nearly perfect conditions, and it is no more conspicuous than many other manmade objects.\n\nOne shuttle astronaut reported that "we can see things as small as airport runways [but] the Great Wall is almost invisible from only 180 miles (290 km) up." Astronaut William Pogue thought he had seen it from Skylab but discovered he was actually looking at the Grand Canal near Beijing. He spotted the Great Wall with binoculars, but said that "it wasn't visible to the unaided eye." An Apollo astronaut said no human structures were visible at a distance of a few thousand miles. U.S Senator Jake Garn claimed to be able to see the Great Wall with the naked eye from a space shuttle orbit in the early 1980s, but his claim has been disputed by several professional U.S. astronauts. Chinese astronaut Yang Liwei said he couldn't see it at all.\n\nVeteran U.S. astronaut Gene Cernan has stated: "At Earth orbit of 160 km to 320 km high, the Great Wall of China is, indeed, visible to the naked eye." Ed Lu, Expedition 7 Science Officer aboard the International Space Station, adds that, "...it's less visible than a lot of other objects. And you have to know where to look."\n\nNeil Armstrong also stated: "We could see continents (on Apollo 11), could see Greenland. It stands out, just like it does on the globe in your library, all white. Antarctica we couldn't see because there were clouds over Antarctica. Africa was quite visible, and we could see sun glint off a lake. It might have been Lake Chad. I'm not certain which lake it was, but we could catch that reflection, sun reflection…. But I do not believe that, at least with my eyes, there would be any man-made object that I could see. I have not yet found somebody who has told me they've seen the Wall of China from Earth orbit. I'm not going to say there aren't people, but I personally haven't talked to them. I've asked various people, particul

China is superpower and this is a long time ago fact!\nBut because they are much people and they have nuclear weapons this doesn't means that they are ready to force the rest world to accept them as superpower. They need to achieve many things in politics in justice in health-care in technology and education!
