Tencent's hugely popular online game "King of Glory" received heavy-handed criticism from Chinese media as being poison to young people.
The result was quite hurtful to Tencent, as its Hong Kong stock dropped 4.1%, losing 14 billion U.S. dollors' worth of market value. The loss fueled a 1.5% drop in the Hang Seng Index as a whole.
King of Glory is a multi-player online battle game. With more than 200 million users worldwide, the gaming app was the most downloaded app in the world on the iOS App Store during the first quarter of this year.
It is thought to have about 50 million active users every day, with 20% of them born after the 2000.
Some have criticized the game as being addictive for the younger gamers, and this scorn has spread across major social media platforms in China.
The people's daily wrote on its website that "the game's content is a twist of values and historical views" claiming that young people's minds and bodies are being ruined by the game.
