But you don’t want them hitting you in the face
Literally: flower – bird – wind – moon
Alternately: The beautiful scenery of nature. By extension, the hyper-indolent aristocratic pastime of gazing out at gardens full of carefully-arranged “natural” scenery while composing poetry, drawing pictures, practicing calligraphy, and so on (and probably drinking). Modern usage tends to focus on expressing the beauty of the natural world.
Notes: There are many variants on this theme. Other elements that may appear are morning (朝 or 晨), evening (夕), dew (露), snow (雪), or seasonal words – especially spring (春) and fall (秋).
This particular compound comes to us from the Fuushikaden (風姿花伝), an early-15th-Century CE treatise on Noh drama by playwright Zeami Motokiyo.
