As we all know, border(边界) safety is very important to a country. In China, many common people, besides soldiers(军人), are doing what they can to keep the border safe, Wei Deyou is one of them.
1 In 1964, Wei, a soldier in the army, went to Xinjiang to keep the border safe. Years later, when the other members left for other places, he chose to stay. 2 He worked as a border keeper while keeping some sheep to support his family. Every day, he rode a horse or walked along the border. He took everything about border safety seriously. 3 当他发现任何不同寻常的事情，他会及时打电话给警察局。 It was really hard work.
One cold winter day in 1987, when Wei was on his way home from work, a heavy snowstorm came. He lost his way and walked for several hours. He nearly lost his life. Luckily, some soldiers saved him. Another day in 1992, his 400 sheep were driven away or killed. 4 He knew some people hated him because of his strictness.
Wei has been working in Xinjiang for over 50 years. 5 无论他过着怎样艰辛的生活,他从不放弃。 These years, he has walked about 200,000 kilometers along the border. He has also found many new ways to keep the border safer. For his excellent work, he has been given some prizes. He is a model for all of us. Now he is 77 years old. He still keeps working there. Just as he said, “It's my duty to do the job. Border safety is the most important.”
