Being a firefighter is a way to give back to society, said Zhang Jiagang. "My grandma gave me a second life and the firefighters who helped me gave me a third life."

In May 2020, Zhang prepared a surprise for his grandma and grandpa during his vacation - taking them to shoot wedding photos. But his grandpa couldn't make it due to his physical condition, so he took his place and finished the shoot.

Now Zhang Jiagang and his colleagues are providing financial aid to two impoverished students. "I will try my best to make the students feel the warmth and kindness of society," said Zhang.
