In the classic 1962 book by Lee Ying Arng, "The Secret Arts of Chinese Leg Manoeuvres" , Lee goes through some basic background of the Chinese Martial Arts where he specifically mentions the categorization of 36 throws, 72 joint locks, 18 weapons, etc.
I have seen these specific numbers repeated elsewhere, a list of the 18 weapons is easily found (such as here)
And the 72 joint locks I believe is fully represented in the 1930's classic book "Shaolin Chin Na Fa".
However, I have never seen anything regarding the 36 throws. Does it exist? Or was it a number made up by Lee Ying Arng and just repeated by other authors over time?
Thanks
