Then check out
Koshi nage or sukui nage????
Then there is Donn Dreager's book on Budo and Bujutsu (Vol.2 I think) that speaks about Oshikiuchi, the forerunner of Daito Ryu Aikjujutsu and it's philosophy of Aiki in-yo ho (Harmony of energy based on yin/yang) which came directly from Chinese Taoism.
All together, these things make the argument interesting for a Chinese link to O-Sensei and his aikido.
