There was an old rich man who was very worried about the future of his spoiled son. Though he had a large fortune, he was afraid of the harm he would do to his son. He thought it better to teach himself to struggle than to leave his fortune to his children.

        He called his son and told him how he had come from nothing and worked hard to get to where he was today. The story of his father touched the young man who had never been far from home and inspired him to struggle. So he made a vow: “If you do not find the treasure will never return home.” The young man built a strong ship, in the relatives and friends of the send-off in the sea. He sailed through the treacherous waves, past numerous islands, and finally found a tree in the rain forest. The trees are more than ten metres high, and there are only one or two in a rainforest. Cut down this kind of tree, after a year in the world let the skin rot, leaving the dark part of the wood heart, will give off a matchless fragrance. The young man thought: this is really incomparable treasure! The young man took the tree to market for sale, but no one came to buy it, which troubled him greatly. It happened that someone was selling charcoal at the stall next to him, and the peddler always sold out quickly. At first, the youth were unmoved. As the days passed, his confidence finally wavered. He thought: “Since charcoal is so easy to sell, why don't I turn the incense tree into charcoal to sell it?”
