    A bottle of water may not seem much to you, but thousands of bottles will be of great help for people who live in drought-hit areas in China.

    Since last autumn, there has been very little rain in Southwest China. Some places, especially in Yunnan, Guangxi, Sichuan and Guizhou, have experienced a serious drought. Crops died, the land cracked(裂开) and wells and rivers died up. More than 20 million people are having difficulty finding safe drinking water.

    After learning about the drought, many people around the country helped by giving water, money and other things.

    The serious drought has also made students realize the importance of saving water. Students from Nanshan Middle School in Huizhou, Guangdong, went on to the street to tell people to take part in water-saving activities.

    "I've heard that some children in drought-hit areas don't have enough drinking water. I feel really sad about that," said one student. "I decided to take a shower twice a week instead of every day to save water." He said.
