Why is Wen Xin Diao Long called Wen Xin Diao Long?

The people upstairs have elaborated on this book. Let me explain the title:]

Liu Xie explained in the Preface to the Carving of Dragons by Wen Xin that Wen Xin means "writing for the purpose" and "carving dragons" refers to the story of the Warring States period, which was known as "carving dragons" and was good at oral argument, as fine as carving dragons. On the whole, Wen Xin Diao Long is equal to "the essence of article writing".
