Your stats could be based on different styles. Crane, Monkey, Tiger, Mantis, and Snake. Or if you're going more abstract, traditional martial arts values, like Spirit, Grace, Iron, Breath, Chi, Balance, Precision, etc.
If you're going for the classic kung-fu feel, you might want moves to recreate those classic movie moments. "When you strike the enemy's lieutenant in battle, roll+precision. On a 10+, after a brief and silent pause, he falls where he stands, dead from your one specific technique. On a 7-9, he's disabled or hurt, but now twice as determined. On a miss, your technique was telegraphed and is perfectly countered."
Or, "When you fight through the enemy's henchmen, roll+iron. On a 10+, you suffer little harm from any of them, finish each in one blow, fight through to where you want to go, impress or dismay the enemy, disarm one them and take their weapon, etc."
Or ways to challenge other characters to duels, inspire oppressed villagers to rebel, push on despite injury, meditate for guidance, be a quiet serene kung-fu guru, a sloppy wobbling drunken master, a precise practitioner of pressure points and chi flow, a hard-bodied and stone-fisted hardass with a permanent frown when he's not shoving his palms into buckets of hot sand, it can go on. Depends on the world you imagine, I guess.
