With the development of our country, all kinds of bridges have been built over the rivers, lakes and seas. And then a special team appeared. They accepted the task of doing an underwater "physical examination" for the bridge. In 2021, Zhang Beiyu became one of them. There are other 12 people in this team besides Zhang. Members in this team are young and their average age is about 28.

Zhang Beiyu loved swimming when he was a child. He practiced hard and had lots of trainings. At the age of 23, he successfully got this work. To be a good worker, he still needed many kinds of practice. The required various professional trainings before the beginning tasks. So he needed to pass the exams of theoretical(理论的) and practical courses. After that, he was allowed to begin a task. For the first time, when Zhang Beiyu carried on a task, he asked his colleagues( 同事) to help him take a video before starting to work. After the work, Zhang Beiyu sent the work video to his parents to share the joy of realizing his dream with them.

"I always dream to become a hero one day. Now I understand that everyone can become a hero as long as they work hard to realize their dreams and know their responsibilities clearly. " Zhang said happily. In 2022 Spring Festival travel rush(春运), Zhang volunteered to help people and made sure everyone could go home safely.

Although he was a green hand in this team, he thought he not only wanted to do testing underwater, but learned from the most difficult work.

In the past 4 years, this young team has travelled and dived( 潜水) through 12 rivers across the country and successfully checked 88 bridges.

"Today, our younger generation(一代) will use the power of science and technology to build a better future for our country." Zhang Beiyu said.
