I am not a huge fan of Chinese history, so I can't tell you if you will like this book from that perspective. However, I am a college student that had to write a ten page history paper on China. I bought this book because I needed primary sources that covered foreign relations in China during certain dynasties. I was very pleased to find many useful sources for my paper, and I can tell that there are many more useful sources for other categories of Chinese history.
So basically, if you frequently find yourself in situations that require you to quote and cite historical Chinese documents, this is probably a good book to add to your library. I know that I will keep this book for a long time, because I have another Chinese history class in the Fall :)
