Well I was only kidding really, but it is a serious business for a lot of Chinese people.

For us it might be just something we see in "chop-socky" films, but China has several centuries of tradition tied up with it and it hepled protect their peasants from frequent invasions in the past.

It's a very important component of Chinese culture - most Chinese folk heroes are Kung-Fu masters (although the term "Kung Fu" itself is a fairly recent invention - Wushu is probably more accurate )so they tend to be a bit sensitive about it, hence this Shaolin vs Ninja business.
