Safety must be watchword for school buses

A 4-YEAR-OLD BOY died after being locked in a school bus for nearly eight hours in Wuhan, Central China's Hubei province, on Thursday. Beijing News comments:

Last summer, four similar tragedies happened in North China's Hebei province within 15 days, which prompted the Hebei education and public security authorities to organize a sweeping campaign in the province to deal with the issue.

The negligence of the kindergarten staff, and the unprofessional management and poor supervision of the kindergartens were found to be the main causes of the tragedies.
