Editor's Note: Communist Party of China members who work in the fields of electricity, railways and aerospace met journalists and answered questions about ensuring safety and space exploration on Monday.

I've been honored to see many high-speed railways open one after another during my 20 years of work. I'm grateful for the chances I've been given to learn, grow and thrive, and now I'm willing to pass on what I have learned to the young, teaching them skills as well as appreciation for society and the country. We will continuously contribute in our roles to step up China's transition from high-speed to high-quality growth.

-Bai Zhiyong, senior survey technician with the fifth branch of China Railway First Group
