Liu Zhijian, 65, is teaching disabled people to dance as a volunteer in Beijing. In the past eight years, she has taught over 100 people with different kinds of disabilities.

Liu was a teacher before. She began to step into the world of dance after her retirement (退休). When she was volunteering at the Chinese Braille Library in 2013, she met some people with disabilities who were passionate about dancing. Touched by their strong love for dance, Liu decided to lend a helping hand by setting up special dance classes.

Many of Liu’s students had to move around in wheelchairs (轮椅). ________ But Liu was so patient that she taught them step by step. So far many of Liu’s students have showed their talents on stage (舞台). Some have even won in dance competitions across the country, making their dream that once seemed out of reach come true.

Liu spends most of her time on volunteer service. She hopes more young people could join her to help people in need.

With people’s help from all walks of life (各行各业), the wheelchair dancers can now practice dancing at customized venues (定制场地) for disabled people. They can also learn from young and talented dance teachers.

Anderson Carey is 12 years old. One day, he saw a magazine article that interested him. It was about prosthetics (假肢), which can be used to replace a missing body part, like a hand, arm or leg.

The article said people are using 3-D printers to build these devices (装置). Anderson thought this was very cool. He wanted to learn more about it. So Anderson talked to his science teacher, Dr. Holly Martin, about building a prosthetic together. The timing was perfect. Martin had just heard about a group called Enabling the Future. This group asks volunteers to help build robotic arms and legs. The volunteers build them for people who share their stories on the website.

Anderson and Martin looked through the website together. They decided to help a man from the country of Romania. His name is Comel Crismaru, who lost his leg, hand and part of his arm.

In February, Anderson and Martin got to work. Building the robotic arm was not easy. Anderson had some problems. He had hoped to use a 3-D printer at his school. One of the pieces for the arm was bigger than the size of the printer, though.

Soon Anderson had an idea to solve this problem. He reached out to a 3-D printing company in Woodstock, Georgia. The company agreed to help. Anderson and Martin could use their big 3-D printers. After that, Anderson worked on the arm for about three months.

Anderson and Martin sent the arm to Crismaru in May. In August, they received a note. It was from Crismaru’s son. He thanked Anderson and Martin for their help.

Martin said she hopes children and grown-ups who hear about Anderson’s projects will realize that it may be hard to change the world, but they can start with small acts. Some of these can help a person in a “huge way”.
