The photo was taken in front of the Vinh Trang Pagoda at Mekong River of Vietnam, one of the undeveloped areas of Asia. Under the unbearable tropical weather,the face of the woman in the middle who sells hats was covered in clothes, the lack of expression contrasted with the rich expression of a tourist next to her. On the left, another vendor drank water from a bucket. The woman in the middle made such a hard living. People passed her by, hardly any income for her.Yet the tranquility and toughness of her moved me.
