[The Fact | Reporter Choi Joo-bin] “Happy Changbin Day!”

Idol weekly ranking site 'Fan N Star' is holding a surprise support event starting the 21st to celebrate Stray Kids Changbin's birthday. It is a global fandom project where advertisements celebrating his birthday are posted in various places.

The success of the Changbin birthday celebration project is confirmed by the number of rainbow stars (can be collected on the site) donated by fans. If more than 20,000 stars are collected, a congratulatory advertisement will be held.

When the number of stars reaches 55,000, a congratulatory video will be shown on the CM board at Hapjeong Station of the Seoul Subway. When 50,000 stars are collected, a congratulatory video will be displayed on the Shinjuku Shin-Okubo electronic display board in Tokyo, Japan. In addition, special gifts such as Hongdae M Screen, Jamsil large digital display board, and Seoul bus advertisement are prepared.

The event will continue until July 28th, and you can participate in the 'ADs.' of the 'Fan N Star' website.
