码

她把刚买的书整整齐齐地码在了桌子上。

She stacked the books she had just bought neatly on the table.

货架上的商品码得很高，拿的时候要小心。

The goods on the shelves are stacked very high, so be careful when taking them down.

这两码事，不能混为一谈。

These are two different matters and shouldn't be confused with each other.

我跟他说的根本就不是一码事，你误会了。

What I told him was a completely different matter; you've misunderstood.
