Second line of 《
木兰辞》 (The Ballad of Mulan, Northern Wei / Northern dynasties, 5th-6th c., preserved in the Yuefu Shiji), the foundational text of the Hua Mulan legend:
唧唧复唧唧,
木兰当户织。
不闻机杼声,
惟闻女叹息 (Click-click, click-click — Mulan weaves at the door. Not the loom's clatter do I hear, only a girl's sighs). Memorized by mainland schoolchildren; the source of the Disney Mulan character.
