Video: Long March done Jay Chou-style

Here's an interesting mash up between a Cultural Revolution-era Long March opera and "Ninja" by Jay Chou, created - if the video's to be believed - by Lee Tang (李唐) from Lu Xun Academy of Fine Art two years back. Is the song choice supposed to be a little ironic, considering one of the parties the Long March ended just around the beginning of the second Sino-Japanese War?
