香港人做SM練習生

我有個朋友今年就黎15years old 好想做sm練習生,佢識好多韓國團體嘅舞(snsd : i got a boy ,the boys , apink :nonono 4minute :what's your name , miss a :i don't need a man ,bad but good ,hyuna :bubble pop sister : give it to me , alone 2pm: a.d.t.o.y 等等)佢諗住自己排兩隻舞之後錄完send 去 sm 公司 但係佢有d野想問:
1: 佢係想做歌手,佢唱歌都唔係話五音不全 感佢寄野過去寫舞蹈部門定歌手部門??
2.如果Audition的話跳舞係咪要自己排??
3.如果想去今年個個深圳Audition 要準備d 咩??
4.sm 個web 到講by post 要寫個個form 咁係邊到download ??
