Fan & Star, a website that delivers idol ranking information, held a special event on June 10 for the group Super Junior Yesung. It is a large advertising project to celebrate his birthday on August 24th.

The success of Yesung's birthday support will be determined by the number of rainbow stars (points that can be collected on the site) donated by domestic and foreign fans. The more stars gather the more celebratory ads will be placed in many places.

The way to participate in the event is simple. It is a way of donating to advertising products that fans want to collect hard-earned stars. Stars can be obtained by doing various activities on the site or completing various missions.
