Which one below is said to be even more severe about left-behind children?

China has 61 million so-called " left-behind children". Economists say this is the price of China’s modernization, and it could jeopardise the next generation of Chinese growth. Children educated in poor rural schools, without literate parents to help them, may be unable to fuel the new innovation-led growth that Beijing is aiming for.

A six-month investigation into a cruise trip. The Eastern Star, found that heavy storms and management errors were the main causes of the tragedy. A State Council investigation team concluded that the incident was "an extraordinarily serious disaster" caused by strong winds and heavy rains that resulted from a squall line accompanied by a downburst, a very rare weather phenomenon. The investigation team has urged government departments and enterprises to improve preventative measures, including a sailing ban on the Yangtze River during extreme weather, a mechanism to issue storm alerts.
