Having played the North American beta last month I can confirm that it pulled out all the stops for Wuxia tropes (of course a heaping helping of Qinggong, but also martial arts manuals, Qi cultivation, and references to the Jianghu), of which I heartily approve. I also suspect the inclusion of golden swallows in this trailer are a reference to Cheng Pei Pei's character in <<Come Drink With Me>>.
