A Magic Paintbrush

Once upon a time, there was a young boy called Ma Liang. He was poor and kind and worked for a rich man to tend cattle. He liked drawing and drew pictures everywhere. One night, he dreamed that an old man gave him a magic paintbrush and asked him to use it to help poor people. When he woke up, he found the magic paintbrush on his desk.
From that day, he used the paintbrush whenever people needed help. When he saw that people had no water to use in the fields, he drew a river and the river came to life. People could bring water from the river to the field and save a lot of time and energy. When he saw it was difficult for people to till lands, he drew a cow and the cow came to life. People could use the cow to till lands very easily. So whenever he saw the peoples' troubles, he would use his magic paintbrush to help.
Then many people found out about the magic paintbrush. But a few days later, the rich man whom Ma Liang worked for heard that the magic paintbrush could turn everything to life. He was a bad man so he had an idea to steal the paintbrush from the young boy. He knew that he could make a lot of money by turning things to life and keeping them. So he sent some people to the Ma Liang's home and took him to the prison. He got the magic paintbrush and felt very happy. Then he invited a lot of his friends to come to his home and showed them the magic paintbrush. He drew a lot of pictures, but they could not become to real. He was as mad as a hornet and his friends was discussing and laughing about that. I'm so embarrassed, rich man thought, why don't these pictures come to life? A few seconds later, the rich man asked some people to get Ma Liang. When the young boy came, he said to him, "If you draw some pictures for me and turn them to life, I will set you free." He must be lying to me, he was a bad man in the village, Ma Liang thought, but I have an idea. The young boy said to the bad man, "I can help you, but you should obey your words." The bad man felt very happy and said, "I want a golden mountain. I will go there to gather gold." The young boy drew a sea first. The bad man was angry and said," Why did you draw a sea? I do not want this. I want a golden mountain. Draw it quickly." Then the young boy drew a golden mountain which was far away from the sea. The bad man saw that and felt very happy. He said, "Draw a big ship quickly. I want to go there to gather gold."
The young boy smiled quietly and drew a big ship. The bad man jumped into the ship first and a lot of his family and friends jumped too. When they reached gold mountain, the young boy drew a large wave and it destroyed the ship. So the bad man and his friends never get back again.
Finally, the young boy lived with his family as happy as lark, and also kept on helping the poor people. So the magic paintbrush was known by everyone.
