Last week, Coconut Water social educators, helped by a group of French volunteers, held  “Brushing teeth and Washing hand “-themed workshop at Wat Roka  primary schools. The students were really happy to learn with group of French volunteers about brushing teeth and washing hand, teach them how to take care teeth, advantages of brushing teeth, how to clean hand and when we need to wash our hand. So, After workshop we hope that students will understand about problem of teeth, love their health and hygiene hand.
