The day we left Dushanzi with no plan is actually the opening time of Duku road. I don't know if it's coincidence or luck... The terrain of Duku road is special, with many sharp turns and steep slopes. There are more than 280 kilometers of road sections above 2000 meters above sea level. Influenced by the natural factors such as snow and ice in winter in Tianshan mountain area, it's only open for five months a year, and it will be implemented from the end of September to May of the next year Up to seven months of winter traffic control.
