Soaking in the hot spring, she really felt 'smooth water washing cream-like skin.'
Tips
history
From 白居易's 长恨歌, describing Yang Guifei bathing at the Huaqing Hot Springs outside Chang'an: 春寒赐浴华清池,温泉水滑洗凝脂 - 'in spring chill she was granted a bath at Huaqing Pool; the smooth hot-spring water washed her cream-like skin.' The erotic opening of Xuanzong and Yang Guifei's tragedy.
usage
凝脂 literally = 'congealed fat/cream,' an ancient metaphor for smooth, pale, perfect skin (see also 诗经·硕人: 肤如凝脂). 滑 here is huá (smooth), not the modern 'slippery/slide.' Almost always paired with 春寒赐浴华清池.
