Mulan: Ha, I see you have a sword. I have one too. They are very manly1 and tough.
I am working on it! Oh,who am I? It is going to take a miracle to get me into the army.
Mushu: Did I hear someone ask for a miracle? Let me hear you say “aaah”!
Mushu: That is close enough.
Mulan: A ghost.
Mushu: Get ready, Mulan. Your serpentine（蜿蜒的） salvation（救助） is at hand!
For I have been sent by your ancestors to guide you through your masquerade（化装）.
Come on. If you are gonna stay, you are gonna work.
Mushu: So heed2 my word! Because if the army finds out you are a girl, the penalty is death!
Mulan: Who are you?
Mushu: Who am I? Who am I? I am the guardian（保护人） of lost souls. I am the powerful, the pleasurable, the indestructible（不可破坏的） Mushu.
