Some observers have faulted the family for not keeping closer watch over their children.
‘‘How could grandparents take care of your child when you are away?’’ asked Beijing parking attendant Liang Hongjin, a migrant worker from Henan province.
However, much of the criticism has been directed at the government and educational system.
The family reported the boys missing Nov. 5. Beijing lawyer Li Fangping said the failure of local officials to launch a proper search was ‘‘horrific.’’
The boys died hours after Xi Jinping gave his first speech as China’s new leader in Beijing’s Great Hall of the People. Xi underlined the Communist Party’s mission to improve the country’s education, employment, social security, housing and health care.
‘‘Our people have an ardent love for life,’’ Xi said in the speech. ‘‘They want their children to have sound growth, have good jobs and lead a more enjoyable life.’’
The boys’ deaths reflect a systematic failure of children services, Beijing Normal University social welfare expert Wang Zhenyao said on state-run China Central Television. The system lacks shelters, social workers and volunteers, and there is poor communication with those in need, he said.
‘‘That’s a blank in China,’’ he said.
