Most commonly seen as the second character in
亲戚 (qīnqi, 'relatives'). The 'sorrow' meaning survives mainly in fixed phrases like
休戚相关 (joys and sorrows linked) and
哀戚 (āiqī, grieving). As a surname, the most famous bearer is Ming-dynasty general
戚继光 (Qī Jìguāng, 1528-1588), defender of the southeast coast against Japanese pirates.
