认

我们十几年没见，我差点儿没认出他来。

We hadn't seen each other for more than ten years, and I almost didn't recognise him.

我不认路，每次来这里都容易走错方向。

I'm not very good at finding my way around, and I often go the wrong way here.

既然做错了事，就应该主动认错。

Since you did something wrong, you should admit your mistake voluntarily.

事情已经很清楚了，可他还是不肯认错。

It was already clear what had happened, but he still refused to admit he was wrong.
