Raft and canoe
In the early primitive society, the primitive ancestors lived on fishing, hunting and catching, and their activities were limited to areas close to the water. They urgently needed something to get more food and resist the damage of floods. Later, the ancients saw the leaves as a boat and saw the floating wood as a boat. They invented the water transportation rafts, also known as the raft. After weaving wooden rafts, there were also wooden canoes and Shanmu boats.
