Subject + 亲手 + Verb + Object
The adverb 亲手 (qīnshǒu) means "personally" or "with one's own hands," emphasizing that the subject performed an action directly rather than through someone else. It combines 亲 (personal/intimate) and 手 (hand). Place it before the verb it modifies to stress hands-on involvement.
