The major events of Chinese railway have been recorded in my lens one by one. I climbed up the mountains at night, rushed to the rivers in the dawn, braved the severe cold in the wind and snow, and probed deep under the scorching sun, all for recording the unimpeded and ever-changing trains. Perseverance is the master impulse of the firmest souls. Real happiness lies in the fruit of labor produced by the railway workers' sweat and toil. I couldn't help but focus my lens on them. The more I photograph, the more I love Chinese railways. It gradually becomes my responsibility to record Chinese railways and the workers. Time－nobody knew how much of it－swept by unheeded and unnoted. The past 50 years seem like a song, as well as a dream. Thanks to the railway, I have had the privilege to travel across the country.
