From
战国策·
齐策一 (Zhànguócè · Qí Cè Yī, 'Strategies of the Warring States, Qi Strategies I'):
连衽成帷,
举袂成幕,
挥汗成雨 — 'their robes joined into a curtain, their sleeves raised into a tent, their flicked-off sweat fell like rain.' The phrase originally evoked the bustling crowds of the Qi capital Linzi (
临淄).
