Chinese literature "Journey to the West"

I have read an article about Chinese literature "Journey to the West" introduced in to London.The author described it as "a 16Th century work of Chinese literature".I think it's not enough so I want to introduced more about it.In China there are Four great piecework of literature which include the "Journey to the West".It's a fairy tale but it's relative to some historical facts.In about 15Th century ,Buddhism was introduced into China from Indian. So many people travelled to India to learn Buddhism by walk.so the most important character in the book was real in history and we call it the journey of redemption.
It's very popular especially among teenagers .20 years ago when it was translated into TV programme ,so many people were waiting in front of TV for this opera.It become one of the most popular and successful TV series.Every Summer holiday,it is replayed on TV for young people until now.
