Fried noodles originated from the Han Dynasty in China has a history of 2000 years, Beijing specialties of a kind of noodles, Korean fried noodles are brought into Korea by the Chinese overseas. Our old Beijing fried noodles is diced meat and onion, ginger and garlic fried fried sauce, plus a variety of vegetables according to different needs can have different variations, the Korean is just sweet sauce and noodles, no meat and no vegetables.

As for why the pronunciation is the same, you can look up the so-called Korean history, Korea (South Korea) in modern times before the Japanese invasion has been China's vassal state to come, with all the Chinese language and Chinese characters, especially the Lee dynasty of more than 500 years, even the family name is taken from the Chinese, the history of the textbooks are also written in Chinese characters. So now it's hard to read the history books of their ancestors. Later, when China fell behind, they began to implement the de-Hanziization, first changing most of the characters into other characters, but found that the pronunciation of the words went to nothing at all, not a language family, after the stupid. Desperately made up a small part of the pronunciation of the majority had to retain this is why many of the modern listening to Korean is the Chinese pronunciation is possible to change a tone, to the present Korean formal occasions of the orthodox instruments still can not escape is the version of the Chinese characters, just do not recognize it.

PS: There's a credible story about the invention of the Korean character shape -- it was King Sejong who was trying to make the characters into some other shape, and when he got burnt out, he looked at the shadow of the moon through the window panes (don't doubt that it was the ancient Chinese kind of panes) and saw the shadow of the ground, and from that moment on, Korea had the Korean character for circle.
