The first public libraries were founded in about the year 1850. Today's public libraries usually have a reading-room, a lending room and a reference room. The greatest and most famous library in Britain is that of the British Library in London. It was founded in 1973 and has over 10, 000, 000 books. It has nearly every magazine, newspaper and book published in Britain and other parts across the world.

In the film, they sang Little Apple when they took part in an American music talent show and they succeeded. Now, life is following art. Chopsticks Brothers will really go to America to sing their song. They will join well-known singers including Taylor Swift. "I did not expect the _ in our film to come true in real life," Xiao Yang said during an interview. "It doesn't seem real. This is another story of dreams coming true for 'old boys'," said Wang Taili. This is the first time a Chinese Internet song will be on the international stage. Little Apple has been more and more popular on China's Internet. Its MP3 received 579 million hits. And people have watched the music videos 823 million times on China's Internet. The song has had at least 500 million listeners around the world. China's famous singer and songwriter Liu Huan said he liked Little Apple during an interview.
