Something you don't want to see it happen , happens before your eyes.All you can do is just stand by helplessly and look on in despair with your eyes wide open.

Ex.: Their son is such a trouble-maker with no prospects. As parents, they can do nothing but watch him helplessly.

There's a saying that "a gentleman doesn't bear grudges against a small man." People in a high position are likely to forgive those in a lower position. Here, Gao Zi Tai means a magnanimous attitude.

Ex.: As a matter of fact, most of conflicts are no big deal at all. If everyone can adopt a magnanimous attitude, they could be easily resolved.
