A trip to Huang Long, Sichuan, China in mid-October, and I spotted this modern day coolie; a middle-aged man in his 50s, along with 4 others were carrying loads of goods weighed at about 80kg or more. They were walking along the street towards Huang Long National Park. I think they were delivering stocks to stalls located in the mountain with height above sea level at more than 3000m. With no proper mode of transport to deliver up to the mountain, and at high air pressure with thin oxygen level, these men are more fitter than you and me. It's pretty tough task actually for an average man, but you just gotta respect them for their perseverance and strong determination, all because to make a living.
