Editor's note: In China, travelers usually opt for long-distance buses as their preferred mode of transportation to areas where no train passes through. These sleeper buses offer passengers a certain amount of comfort and flexibility. However, in late 2011, authorities announced they were canceling the production and sale of these buses due to their frequent accidents. The Chinese transportation and safety authorities have now ordered a strict investigation into long-distance bus safety after a major road accident claimed the lives of 36 people on Aug. 26, 2012.
