Two recent videos of Chinese teenagers committing suicide have rung the alarm about the mental health of the country's youth and the reasons leading some to go down such a fatal route.

Both cases were related to school problems that strained family dynamics, and experts say that better communication could have prevented these tragedies.

On March 29, a 15-year-old middle school student in southwest China's Sichuan Province broadcast live his suicide by drinking pesticide.

His last words were, "I will never forgive my teacher even though I become a ghost." The boy had quarreled with a classmate and was scolded by his teacher and then his parents over the phone, without a chance to explain himself.

On April 17 in Shanghai, a 17-year-old boy jumped off a viaduct in front of his mother and died. According to local authorities, the boy leaped to his death after he fought with his parent about his conflicts with classmates.

The two videos sparked heated online debate over parent-child relations. Some said adults need more empathy, while some blamed the suicide victims.

The alarm over the mental health of adolescents was also raised in a recent study co-conducted by the China Youth and Children Research Center and the Institute of Psychology of the Chinese Academy of Social Sciences.

It found that nearly a third of young people aged between 14 to 35 years are at risk of feeling depressed. Some 7.7 percent of teenagers aged between 14 to 19 are at high risk.

That's partly because some teenagers are emotionally immature and don't know how to cope with pressure, said Sun Hongyan from the China Youth and Children Research Center.

And for the two cases cited, many pointed to a lack of understanding and communication between teenagers and their parents and teachers.
