If Wei is really serious about her dancing, this Arthur Murray move should be exorcised and a visit to the Copa should be in order. Study the Latina dancers, and look for a lady with very skinny legs, usually wearing pants, with thick black hair and a great big smile on her face. There's no effected hand and arm gestures, just flying feet, great rythm and plenty of genuine passion for the music, not for how she looks when she's dancing. Then, you'll have something, if you can emulate la reina de salsa...
