Dongcha (Woonden Cart)

In the book “Yungwonpilbi,” which contains information about Joseon’s military technology, a wooden cart used to transport cannons is mentioned. In the earlier book "Jixiao Xinshu" written in the Ming Dynasty, there is also a record that when used on land, the cannon's angle was adjusted by digging a hole, tying it with ropes, and then securing it with stakes.
