Casualties and convoys on the road trips from hell

When China was fighting for its life during the Japanese occupation, more than 8 million overseas Chinese from across the world who rallied to help the country.

Among them, about 3,800 drivers and mechanics from countries in Southeast Asian volunteered to return to China to assist with transportation on the Burma Road, the country's only lifeline for international aid at the time.

Although more than 30 percent of the volunteers were killed on the dangerous 1,154-km mountain highway between 1939 and 1942, the operation transported nearly 500,000 metric tons of military supplies to China from Myanmar, then known as Burma, an average of 300 tons a day.
