Ancient China produced what has become the oldest extant culture in the world. The name 'China' comes from the Sanskrit Cina (derived from the name of the Chinese Qin Dynasty, pronounced 'Chin') which was translated as 'Cin' by the Persians and seems to have become popularized through trade along the Silk Road.
A frame of reference is a point or set of fixed points relative to an object describing a motion, and affects on the movement you perceive for the object.
For example, if you throw a stone from the window of a car, you'll see a different trajectory depending on whether you take the road or the car as the frame of reference. On the first situation you'd notice a trajectory, while from the car you'd see the stone almost falling to the ground only.
