Översättning - Kinesiska (förenklad)-Franska - 总有一句誓言是真心的。

Hello.

Can you help me to validate this translation?

My bridge in english:
There must be a sincere promise.

Thank you.

My French is poor, so I cannot make sure.

It's the reason why I translated the french version in english.

Her translation is perfect.

Thank you very much.
