Alongside walking partners Yang Wendou and Li Bing, Salopek has emerged from the mountains of Gaoligong and continued east.

Over the past few weeks, they’ve been trekking the Burma Road, one of the greatest feats of engineering from World War II. It might be named after Burma (modern-day Myanmar) but this Burmese road took 200,000 Chinese laborers to build and winds through Yunnan in China.

More than 600 miles long, the road’s construction cost roughly three lives per mile. Now, this road has taken Salopek east to the Yunnan town of Baoshan.
