High-fashion brand Emporio Armani Hong Kong has launched its first-treasure hunt app, with augmented-reality technologies to enable users to track down a special quarry, Shanghai actor Hu Ge.

Until October 17, the EA Collector app can be downloaded to scan AR images on four Hu Ge posters scattered around Harbour City. Users will then be able to take virtual photos with the Emporio Armani brand ambassador for Greater China and Asia Pacific.

Users who present one of Hu Ge images can redeem a gift at the Harbour City Emporio Armani store, with a limited-edition postcard holder for anyone collecting all four images. There are limited daily quotas for this offer.

Furthermore, there is a a chance to win an invitation to Emporio Armani’s party to meet Hu Ge by using the app to submit a virtual photo with the actor before October 15. The actor himself will choose 10 winners to attend the party, on October 18.

To celebrate the event, a limited-edition Hu Ge Octopus Card will be launched at all Emporio Armani stores across Hong Kong.
