1. Legend of Dai nationality

According to legend, in Xishuangbanna, Yunnan Province, a hunter was the first to discover that the juice of poisonous arrow wood was poisonous. One day, when the hunter was hunting, he was accidentally watched by a big bear. The bear chased him all the time. At last, he couldn't help climbing a big tree, but the bear still didn't give up and was chasing him. Finally, there was no way to go. He was about to be eaten by the bear. At this time, the hunter broke a branch and stabbed the bear who was climbing up the tree, As a result, a miracle happened, but the bear suddenly fell to the ground and died. So after that, all the hunters in Xishuangbanna learned to put the juice of poisonous arrow wood on the arrow to hunt. There is also a legend among Dai people that there was a great flood in Xishuangbanna long time ago. After the flood, people rebuilt their houses. Here came a lot of tigers. The tigers hurt many people, including a man named bohongsha. In order to kill the tigers, he drank a lot of poison. Then his blood was immersed into the ground and grew a tree. The tree absorbed the man's blood and grew into a poisonous tree

2. Indian legend

In the early days, there was a poisonous plant in the place where Indians lived, that is, poisonous arrow wood. People living there often cut a hole in the trunk of the tree to let the juice flow out, and then put them on the arrow to hunt. Later, when the Indians encountered the invasion of the invaders, they smeared the juice on the bows and arrows, and the invaders died immediately. Moreover, they used this method every time and won every time in the future, which frightened the invaders every time and dared not invade again. They kept their homes very tenaciously
