Shi Xinguo, a rural postman in Laocheng town, Xichuan county, Henan province, is affectionately known as "Xiao Shi" by the villagers. Xiao Shi grew up drinking the water of the Danjiang River and has spent the past 25 years delivering mail at the head of the canal. Every day, he watched the clear water flowing northward and dreamed of visiting Beijing. Now, Xiao Shi and his wife have finally made the trip, checking off landmarks like the Great Wall, Tiananmen Square, and Tuancheng Lake, fulfilling a long-held wish.
