Visit Cambodia PKH Trang

In July 2016, I visited Cambodia PKH Trang to see the solar installation at the training centre.

The school children are provide with free breakfast and lunch at school. This is encourage them to attend school.

 A basic dental care is taught to the children by a volunteer dentist.
They have dug a pond to store the rain water during the raining season. This is to provide additional water storage during the dry season.
We visited one of the school children house near the vicinity. In their compound, they have a kiln to make charcoal from the firewood.
Inside the kiln. The firewood are kept inside the kiln with fire for 15 days to become charcoal.
We stay at PKH Aoral, below is a picture of the delicious dinner prepared by the cook. Excellent!

 Time to return home, farewell group picture.
