Chinese authorities have executed Xu Yao, a senior executive who poisoned Lin Qi, the billionaire producer behind the hit Netflix adaptation of Liu Cixin's science-fiction novel 'The Three-Body Problem.' Lin Qi, who owned the rights to the series through his company Yoozoo Games, died in late 2020 after being poisoned by Xu, a colleague within the firm. The case drew widespread attention given Lin's prominence in China's entertainment and tech industries, and the execution closes a high-profile criminal proceeding that had cast a shadow over one of the country's most celebrated recent cultural exports.
