I'm trying to find as much info on this man as possible.
He wrote several books on Shaolin in 1764 and one 1792.

A detailed explanation of 18 Lohan exercise as well as complete manuscripts with explanations of the forms he did.
He is one of the Praying Mantis original people. His form, -praying mantis "hit" six roads-(tang lang da 6 tang), is probably the oldest manuscript of a PM form.

Supposedly, other styles descend from this man which I would like to try and confirm.
