Singer Ong Seong-wu's birthday event is being held at "Fan N Star."

"Fan N Star," an idol weekly ranking site, opened a special project for Ong Seong-wu on the 16th of last month. It is a big advertising event to celebrate his birthday on August 25th.

Ong Seong-wu's birthday event will be held in cooperation with fans and "Fan N Star." Success is determined by the number of rainbow stars (points that will be collected on the site).

When 20,000 stars gather, a congratulatory video will be shown on the CM board of Hapjeong Station in Seoul Subway. When the number of stars reaches 55,000, a congratulatory video will also be upload on Shinjuku Shinokubo's electronic display board in Tokyo, Japan. In addition, abundant gifts such as M-Screen in Hongdae, a large digital display board in Jamsil, and advertisements for Seoul buses are waiting for fans.
