On the 8th, 'Fan N Star', a website that provides information for idol rating held a special event for Jang Won-young. It is a big advertising project to celebrate her birthday on August 31st.
The number of rainbow stars (points that can be collected on the website) donated by fans determines the success of her birthday project. The more stars you collected, the more congratulatory ads are posted in various places.
When 20,000 stars were gathered, a congratulatory video was shown on the CM board (square column) at Hapjeong Station, Seoul Subway. Reaching 55,000 stars, a congratulatory video will also appear on the Shin-Okubo electronic board in Shinjuku, Tokyo, Japan. In addition, gifts such as Jamsil large digital signs, Hongdae M screens, and Seoul bus advertisements are waiting for fans.
