改过

It is incumbent on me to reclaim him.

劝他过是我不容务。

A bad habit in a child should be nipped in the bud.

应该尽早把孩子坏习惯过来。

The thief has amended.

这小偷过自新了。

However, because the villager committed this crime with a secretiveness not in keeping with his thickheaded ness, it remained a "perpetrator unknown" crime.

然而，于该村民一过去笨脑袋，闭口不谈自己罪行，使该案成为悬案。
