Zhihu, a Quora-like Q&A platform in China, is mulling over a secondary listing in Hong Kong after it went public in the US in March this year, a local media outlet reported Saturday. The report says Zhihu plans to submit documents for its share offerings in Hong Kong in January. The Beijing-based company denied the report in a response to local media on Sunday. Speculation around a dual listing comes after the New York-listed firm was summoned by China’s state internet regulator last week for “unlawful release of information.” [Jiemian, in Chinese]
