Southeast Asian Crossbow of the Hmong

Here is my antique primitive crossbow made of bamboo and wood, of the Hmong/Miao/Mao peoples for hunting. The original bamboo prod and bolts were from the late 20th century and is too old to shoot so I made a reproduction bamboo prod of around 50lbs and some reproduction bolts. They are often used with poison to become an effective weapon.

"Throughout the southeastern Asia the crossbow is still used by primitive and tribal peoples both for hunting and war, from the Assamese mountains through Burma, Siam and to the confines of Indo-China. The peoples of the northeastern Asia possess it also, both as weapon and toy, but use it mainly in the form of unattended traps; this is true of the Yakut, Tungus, and Chukchi, even of the Ainu in the east. There seems to be no way of answering the question whether it first arose among the barbaric forefathers of these Asian peoples before the rise of the Chinese culture in their midst, and then underwent its technical development only therein, or whether it spread outwards from China to all the environing peoples. The former seems the more probable hypothesis, given the further linguistic evidence in its support"

Around the third century BC, King An Dương of Âu Lạc (modern-day northern Vietnam) and (modern-day southern China) commissioned a man named Cao Lỗ (or Cao Thông) to construct a crossbow and christened it "Saintly Crossbow of the Supernaturally Luminous Golden Claw" (nỏ thần), which one shot could killed 300 men. According to historian Keith Taylor, the crossbow, along with the word for it, seems to have been introduced into China from Austroasiatic peoples in the south around the fourth century BC. However, this is contradicted by crossbow locks found in ancient "Chinese" Zhou Dynasty tombs dating to the 600s BC.

In 315 AD, Nu Wen taught the Chams how to build fortifications and use crossbows. The Chams would later give the Chinese crossbows as presents on at least one occasion. Siege crossbows were transmitted to the Chams by Zhi Yangjun, who was shipwrecked on their coast in 1172. He remained there and taught them mounted archery and how to use siege crossbows. In 1177 crossbows were used by the Champa in their invasion and sacking of Angkor, the Khmer Empire's capital. The Khmer also had double bow crossbows mounted on elephants, which Michel JacqHergoualc’h suggest were elements of Cham mercenaries in Jayavarman VII's army.

The very first crossbows are likely made during the stone age or Neolithic age, due to the similarity of how a bow is made using a tillering stick. Such primitive bow traps and crossbows can be made with very simple triggers.
