Its name in Chinese is actually "zhen gong fu", simply means "real hard work". This chain locates mainly in the southeast part of China, such as Shenzhen, shanghai... I like their food. Their food aren't like the American fast food which are very greasy and high in calory. They are light and probably more healthy.

And once more, not every one in China knows Kungfu... In fact, very few. But be careful if you are travelling to Dengfeng City of Henan province(which is my hometown), as that's where Shaolin Temple is and Martial Arts are really popular there.
