Hi,
I'm from Vietnam. Can you do me a favor?

Here is a Vietnamese-version of a French song. I've tried so hard for months to find out the original song. Unfortunately, I couldn't. I found this website through google, and a hope raised in me. Since you guys are seemed so familiar with French songs, maybe some of you may recognize the melody. Please help me figure this out. Thanks a lot if anyone can give a hand.

Your sincerely,
Thanh
