Give water, save lives

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

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

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

Last week, every member of the Communist Youth League (共青团员) and Young Pioneers(少先队员) were encouraged to give one bottle of water to the drought-hit areas. Students in primary schools and middle schools quickly joined the activity. In Yuhua Primary School in Xi' an, 900 students bought over 1,000 bottles of water with their pocket money. They also wrote their wishes on the bottles.

The serious drought has also made students realize the importance of saving water. Students from Nanshan Middle School in Huizhou, Guangdong went on 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. They have to drink muddy ( 含有泥土的 ) water. I feel really sad about that," said one student. "I decide to take a shower twice a week instead of every day to save water," he said.

"Military-style" travel has become the latest fashion among Chinese college students, who spend as little money as possible to travel to as many places as they can during the weekend, hardly taking a break or even sleeping.

To save money, they usually catch a normal-speed train on a Friday night, arrive at the destination city on Saturday morning, travel around in the city, sleep at a 24-hour restaurant for a few hours on Saturday, then repeat the same busy schedule on Sunday before returning to their university in time for classes on Monday morning. These young travelersare less concerned with in-depth(深入详尽的) experiences and more focused on checking off popular tourist destinations on their schedule. 

Hu Die, a student at Inne r Mongolia University of Technology, is one such traveler. She put together a 10-day holiday during the recent May Day holiday period and traveled to six cities. 

On April 26, she took a high-speed train to Beijing and then from Beijing to Tai'an, Shandon g Province, to climb Mount Tai. To save money, she spent 4 hours climbing up to the mountaintop rather than using a cable car. After watching the sunrise from it on April 27, she visited Dai Temple at the foot of the mountain. She then went to Jinan in the afternoon, visited Daming Lake and Quancheng Square in the evening, and on the morning of April 28 went to Baotu Spring and Heihu Spring. She traveled to Zibo to enjoy the famous barbecue in the city, went to Yantai and Weihai before May 4, when she arrived in Luoyang, Henan Province. There, she visited the Longmen Grottoes and then returned to her school on May 5.

Most people can hardly imagine how she traveled extensively in only 10days. "We do not think we are doing something ‘crazy' or ‘amazing'. We are young and energetic enough to experience such a tight travel schedule, "she said. "Moreover, when you travel with your friends, you are happy and you do not feel tired. "

Videos of them taking such trips have been posted on social media platforms, such as TikTok, Red, with much praise for their energetic spirit and high ability to achieve their plans. Others, however, question whether such a busy schedule is healthy.
