China's food delivery and online services giant Meituan Dianping saw its shares open 5.7% higher on its trading debut in Hong Kong.
The tech giant, which is regarded as China's 'everything app' raised HK$33.1bn ($4.2bn; £3.21bn) from its Hong Kong initial public offering.
Backed by Tencent, the company offers a wide range of services, from instant food ordering to online ticketing. It also operates a bike sharing brand called Mobike.
Analysts said its successful debut was a good sign for other tech giants planning to list in Hong Kong later this year.
