When you pin something down, it has nothing to do with pinning something up.

首先，pin down和pin up的意义毫不相干。

It's not just the wig. It's pinning her hair up, drawing on her eyebrows. It's a two-person job.

不仅仅是假发 还要把她的头发盘起来 画眉毛 是两个人才能干的活儿。

Meg drew her aside, under pretense of pinning up a loose braid, and said approvingly, " It was dreadfully provoking, but you kept your temper, and I'm so glad, Jo" .

梅格假装系一条松散的辫子，把她拉到一边，赞许地说：“这真是令人发指，但你没发脾气，我很高兴，乔。”
