Shaolin techniques or styles can be listed with certainty, and did they include animal styles?
Yes. Naming martial arts tactics, forms and even entire military units after animals goes back to ancient times. This is well documented. There are 10 animals, connect by legend to Bai Yu Feng in the tradition I practice: dragon, snake, leopard, crane, monkey, pelican, horse/mustang, water buffalo, tiger, elephant. These are not separate sets but are integrated. Other sets include the butterfly (, ; ) but only the monkey really imitates the actions of the animal.
Lastly, does anyone know who was actually consulted during the creation of government sponsored Wu Shu after the Cultural Revolution?
‘Modern’ wushu was developed a decade before the Cultural Revolution and was based on traditional martial arts, as has been pointed out in other posts. I believe the main early members of the Chinese Wushu Association Committee included: Li Menghua, Wang Ziping, Mao Bohao, there were others but they were the key players. Cai Longyun may have been part of the team as well, but I am not so sure.
How much of competition Wu Shu was developed from traditional Wu Shu(a) and real Shaolin Kung Fu(b)?
What are you looking for? percentages? I’m not sure what you are asking, but yes modern wushu was developed out of traditional northern styles during the early 1950’s - note that this was well before the Cultural Revolution. The base style was Hong Chuan Quan (long first). Our tradition claims that Xiao Hong Chang Quan , and Da Hong Chang Quan were the basic testing sets of Shaolin for generations. Our sets have some resemblance to those practiced at Shaolin today, but are much more like northern long fist.
My teacher trained during the late 1920s and his teachers trained in the mid and late 1800s in Henan. When they left for Beijing Luoyang was in hell of a mess the Nian rebellion, extreme droughts, floods, high unemployment rate and widespread use of opium had crippled the region and made life there next to intolerable.
