A group of us signed up for an overnight stay on a junk in Ha Long Bay, Vietnam, and had the option to visit a fishing village before we got back to port. Five USD per person was the cost of the fishing village/cave tour. Our tour guide explained that the fishing village puts the money from these tours toward the cost of hiring a teacher from the nearest town to provide their children with an education. We transferred from the little shuttle boat that was attached to the side of the junk to an even smaller boat owned by one of the families in the fishing village. A father and son, both locals in the village, took us to see a few of the nearby caves.
The father explained that he has many sons and this one driving the boat is his youngest. His mother is 102 and is still alive and well — we passed her on the way back. She waved to us from her squatting position on a houseboat. There are seven generations of this family living in the fishing village. The men and women tend to marry people from the same village. They catch a variety of sea food to sell for income and store it in baskets and nets in the floating decks of their homes.
