Sprezzatura 刻意疏忽

Tranquil Consciousness of effortless superiority

排練過的即興行為，深思熟慮過的粗心大意，有說服力的、熟練的順其自然。

A certain nonchalance, so as to conceal all art and make whatever one does or says appear to be without effort and almost without any thought about it.

An easy facility in accomplishing difficult actions which hides the conscious effort that went into them

Studied carelessness
