I want to help this lovely couple in a local village,Vietnam

I have been travelling through Vietnam for the past 2 weeks. I have come across all kinds of lovely and pure people. My trip lead me to visit this small village. It is a great tourist attraction in Vietnam with beautiful landscapes and countryside activities. Riding a bike in this area is one of the most surreal activity you can do while you breathe in the freshest air. 

This couple gave us a personalised tour of the whole place and were so nice to us. I wish I could do more to help them do a little better or at least make them happier.

I can’t do much by myself but with everyone’s help maybe I can make a little difference. And little difference contribute to something much bigger in the long run.
