 The Chinese thinking about qing basically follows an objective-to-subjective trajectory. It begins with philosophical investigations into the nature of the myriad things or wanwu 萬物 (ten thousand things) during the late Spring and Autumn period and the early Warring States period (roughly the late sixth and fifth century BCE). This is followed by a shift of attention from the objective nature of the things to the subjective nature of humans—their emotion and moral nature—during the middle and late Warring States period (roughly fourth and third centuries BCE). From the Han onward, the locus of qing discussions shifts from philosophy to music and literature, with emotion being qing’s core referent.
