Peaceful scene of red-shanked douc langurs enjoying the cool flowers of Son Tra

From April to early May, the branches of the purple-colored Than Mat flowers swaying gently in the wind are brightening up the corners of Son Tra Mountain, Da Nang City. However, what attracts people, tourists and even photographers is the image of groups of red-shanked douc langurs - the primate queen - sitting perched high up, peacefully enjoying their favorite early summer dish, Than Mat flowers.
