The development of PLA's cruise missles

Can anyone provide informations about the HN, Hon Niao series Land attack cruise missles? Read from an article of Jane’s that it has three model until now. HN1, HN2,HN3.It can be launched from land vechicle, submarine, or from a bomber.
Also I read from Washington Times last year that PLAAF had launched an air launching version cruise missle from a H6 heavy bomber as a standoff weapon.

HonNiao means Redbird in Chinese.

Anyone can tell more…?
