恤ng Son was a prehistoric Bronze Age culture in Vietnam centered on the Red River Valley of northern Vietnam. At this time the first Vietnamese kingdoms of Van Lang and 聈 L?c appeared. Its influence flourished in other neighbouring parts of Southeast Asia from about 500 BCE to 100 CE.

One side of the Ha Dong axe blade is decorated with a vivid hunting scene by boat. We see a curved-prow boat with two hunters standing on the boat; raising javelins in their hands over their heads as if they are going to throw them. Under the boat there are two deer with large antlers; one with a slender belly and the other with a big belly; probably manifesting the male and female deer.

They are tensing their legs to run away. In front of them is a hunting dog; with a slender belly and long muzzle; which is trying to prevent the deer from running away.
