Every time Han Qiming is asked about his bike journeys, he feels proud and can't stop telling interesting stories.

Han, 71, a retired engineer from Harbin, capital city of Northeast China's Heilongjiang province, finished an approximately 6,000-kilometer bicycling journey through Vietnam, Cambodia, Thailand and Laos together with five fellow travelers two weeks ago.

Starting from the Chinese-Vietnamese border port of Dongxing in South China's Guangxi Zhuang autonomous region, the six cyclists, aged from 55-71 and hailing from Harbin, finished their journey in 74 days.
