Overseas listings are popular with China's tech firms. Many of the tech giants in China are US-listed such as Alibaba, JD.com, Netease, and Sohu.com. Two months ago, Huami Corporation, the smart wearable device partner of Xiaomi, filed with the US Securities and Exchange Commission for a 159 million US dollars IPO. According to Renaissance Capital, in the year 2017, 16 Chinese firms went public and collectively raised 3.4 billion dollars on US exchanges -- that's more than double the number in 2016 and tech IPOs were among the best performers, including the online micro-credit provider Qudian, raising 900 million USD in an IPO that was priced at 24 USD, the biggest ever US listing by a Chinese fin-tech firm.
