Friends,
Those interested in the forms of Northern Praying Mantis as taught by master Wong Hon Fan may be interested in my new book found here:

http://www.blurb.com/books/1485237

It contains a translation of the quanpu (fist songs) for fourteen of the Northern Praying Mantis empty-hand sets.
The first fifteen pages, including the table of contents, can be viewed at the above link.

Regards,
Richard A. Tolson
