Fan & Star, an idol weekly ranking site, opened birthday support for Jiyeon, a former member of the group T-ara, on the 30th of last month. As of the 13th, 13 days after the event, 13,050 rainbow stars (points that can be collected on the site) have been gathered.

Jiyeon's birthday project will be successful in a separate number donated by domestic and foreign fans. The more stars there are, the more celebratory advertisements there are in various places.

Participation in the event is available at the ADs section of Fan & Star's website. It is a way of donating the stars collected by fans to advertising products that they want. The number of donations is unlimited and another product can be added.

Currently, Jiyeon's birthday support includes abundant products such as electronic boards at subway stations in Seoul, large digital electronic boards in Jamsil, Hongdae M-Screen, Seoul bus advertisements, and Japanese electronic boards.
