Fan & Star opened Hong Ji-yun's birthday event.

Fan & Star, a site that delivers singer ranking information, is carrying out a special project for Hong Ji-yun on January 6th. It is a large advertising event to celebrate her birthday on March 3rd.

Hong Ji-yun's birthday event will be held in cooperation with fans and "Fan & Star." Success is determined by the number of rainbow-specific points (points that can be collected on the site) that gather in the project.
