I just got to know that Xin Xian He Shen Zhen ( 新仙鹤神针 ) is the revised version of Fei Yan Jing Long ( 飞燕惊龙 ).

To those who have read both versions:-

1. What are the difference between the 2 books (except for the name changes of the chars and the book title)?
2. Which book is better?

FYJL has 30 chapters more than XXHSZ.
