As a railway photographer, when looking back on the way in the past, I find both joys and sorrows, sufferings and happiness, failures and gains. This is the most impressive job for me among all my long-term and part-time occupations. Be it the railway on the prairie, plateau or the Gobi Desert, I have photographed them and they occupy a major fraction of my deepest memory－from the plains to the snow-covered plateau at an altitude of more than 5,000 meters, from the southern seashore to the far north, and from the northwestern hinterland across the country to Hong Kong, pearl of the East.
