Once upon a time, there lived a wise man. Everyone loved him. His son, however, was very lazy and did nothing all day. 

The wise man was worried about his son's future. One day, he said to his son, "I want you to go to find some treasure(财宝). I have drawn a map to guide you. " Then he gave his son a bag. There were clothes, some food, a little money and a map in the bag.

The son set out(出发) on his long journey the next day. He had to travel across forests, rivers and mountains. Along the way, he met a lot of people. Some helped him with food, and some with a place to live. He also met robbers(强盗) and lost much money. He saw changing landscapes(风景) and experienced different kinds of weather. 

Finally, after a long year, he reached the place of treasure. He spent two days looking and digging for the treasure, but found nothing. 

Feeling sad, he decided to go back home. On his way back, he experienced the same changing landscapes and seasons. Sometimes, he would stop to enjoy the beauty of nature. He also learned to hunt and make meals. He had to fix his own clothes and the tent himself. He was now able to tell time by the sun and protect himself from wild animals. He met the same people who had helped him earlier. This time, he stayed and helped them in order to repay them. 

When he reached home, he said sorry to his father for not finding the treasure. 

"There wasn't any treasure in the very first place, my son," the father answered with a smile. "But I think you have found your life's true meaning. "
