Karen Wong set up an online business, which started in the US and Australia, providing a luxury pop-up picnic service. Spotting a new business opportunity during the Covid-19 pandemic, Wong brought the idea back to Hong Kong from Perth in October 2020. The business the 25-year-old launched with two partners offers a one-stop service, from helping customers find a picnic site, setting up the picnic, to packing and cleaning up.
