The Washington Post:

Like his hunt for his parents, Liu’s suicide was first flagged on social media. In a letter over 7,000 words long, posted at 1:02 a.m. on Monday, he responded to online attackers and relayed his experiences of childhood loss, bullying, molestation and depression.

When his death was confirmed by Chinese police, it triggered an outpouring of grief and nationwide soul-searching over cyberbullying, mental health and abandoned children. By Tuesday night, a hashtag of his name had been viewed 2.4 billion times on the microblog Weibo, as many asked how Liu could have been let down so frequently and utterly by society.
