One of the greatest warriors(勇士) of history, Genghis Kahn, came from the Mongolian people. He controlled many countries in Asia and Europe because of his bravery and leadership in battle. This time period was known as the Yuan Dynasty in the 13th and 14th centuries.

Genghis decided to go hunting one day and many of his warriors went with him. Genghis had his favorite hawk on his wrist. The hawk was trained to fly high in the air to look for game like deer, rabbits or wild birds. When his bird flew to the ground, Genghis would follow it and shoot the wild game with his arrows. It was his favorite hobby.

This particular day, game was hard to find. Toward evening, Genghis sent all the men home and decided to go another way by himself. He even let his hawk go, thinking it would fly home as well. He became thirsty so he stopped by some rocks where he noticed water was dripping. He took a cup from his pack and filled it slowly. When he put it to his mouth, he was surprised for his hawk came and spilled (使溅出) all the water in his cup.

He thought this was very unusual so he filled the cup again. The hawk rushed down and knocked the cup free from his hand. Genghis was now thirsty and angry. As he filled the cup a fourth time, he drew his sword to stop the bird interrupting him. As the bird flew down, Genghis killed it but his cup fell deep into the rocks in the scuffle (扭打).

He decided to crawl up the rock of the mountain to find the source of the water. He found a pool and noticed a huge poisonous snake was dead in the water. He realized the hawk had saved his life. His anger had caused him to kill his favorite bird. In his despair (绝望), he promised to make sure of everything before he would become angry again.
