《三只小猪》中的句子：Soon, a hungry wolf came along. He knocked at the door and said, "Little pig, little pig, let me come in."
"No, no, by the hair of my chinny chin chin. I won't let you in."
"Then I'll huff and I'll puff and I'll blow your house in."
这里的by the hair of my chinny chin chin，还有I'll huff and I'll puff 是什么意思？该怎么翻译呢？
