Shenhua is a Taiwanese assassin working under Mr. Chang. She's best known for her deadly close-quarters style, favoring a pair of linked kukri knives tethered together with leather rope—a signature weapon combo. She's also competent with throwing knives and likely has unarmed combat skills, though the anime never really shows her using them; she sticks exclusively to bladed weapons in a fight.
What fans often note about Shenhua is her distinctive broken English-Chinese speech pattern, which shifts between languages mid-conversation in a way that's become pretty iconic for her character. Her personal faith is Taoism.
Professionally, she operates in a complicated dynamic with Revy—sometimes they're rivals, sometimes they work together, depending on the job. The comparison to Shampoo from Ranma 1/2 comes up occasionally when discussing her language quirks.
