chinese martial arts is refered to wu shu, shaolin, wu dang, or whatever else style it is.
but it actually is not kung fu!!! it's by far one of the most widely mistaken phrases that just kept being used that it developed the meaning of martial arts.
kung fu in Chinese just means "great skill" that's all it means lol =p so Chinese ppl can say "let me show you my kung fu" and then u'll end up seeing them doing some really hard math =p
funny ass clip anyway =p
literally, i've seen a monkey do better than them =)
