In mid December, Zeng Lingquan, the owner of a shelter for the mentally disabled in Sichuan province, was detained for allegedly selling mentally disabled individuals from a shelter he operated. In this cartoon, posted by artist Kuang Biao (邝飚) to his QQ blog, four mentally disabled laborers struggle to break rocks in a ghostly quarry littered with strange stones that resemble skulls.
