(HBO) - Setting foot in the primary forest in Nhuoi village, Da Phuc commune of Yen Thuy district, our tiredness seemed to fade away. Under the shadow of old-growth trees, the air was fresh and cool. It was just 2 o’clock in the afternoon, but Truong Duc Hoa, a forest ranger of Da Phuc reminded us to quickly do our reporting as dawn would fall quickly in the forest.
