Well,neither do i really believe in Oyama's story about taiji fighting,the most famous taiji elder in Hong Kong is Wu Gong Yi of Wu style taiji,Oyama is such a good story teller though~~~:)
According to what it had read,they said that Sabaki was influenced by aikido instead of taiji,weird~~~
It is also believed that Oyama also met Wang Xiang Zhai of Da Cheng Quan and incoporated it in to his karate~~~

Anyway the crane.50.meg website belongs to a senior in the place where i have been learning MT,he was also a nidan in Kyokushin Karate and had learnt Baji of liu Yunqiao lineage~~~
