What is the surprise birthday gift from fandoms?

Idol fandom's play space "Fan & Star" held a birthday event for the group X-won Kang Min-hee and Kim Yo-han on April 23. It is a big ad project to celebrate the two people's birthdays on Sept. 17 and 22.

This event is a support-type event where fans from home and abroad can participate together. It will add meaning to the message as it will be posted in some advertisements by fans themselves.

If 50,000 stars (the point that can be collected on a site) are gathered in the project, a congratulatory video will be sent to the CM board at Hapjeong Station (a square pillar) on Seoul Subway Line 2. If the number of stars reaches 100,000, a congratulatory video will also be sent to SM Board (wall) at Gangnam Station, Subway Line No. 2.

Once 200,000 stars are filled, the congratulatory video will also be shown on the front panel of the waiting room at 43 stations on Subway Line No. 2. Furthermore, a variety of products are available, including the Apgujeong CGV screen, the Hongik University Multivision, and the advertisement of a foreign-only treble bus.

Currently, Kang Min Hee and Kim Yo Han's birthday project brings together more than 60,000 stars and 90,000 stars, respectively. It is hoped that the team will be able to record a higher achievement rate for the rest of the year amid a flood of congratulations from many fans.

The two's birthday ad project runs through Tuesday and can participate in the "Star Market" section on the "Fan & Star" website.

Meanwhile, the project group X1, which includes Kang Min Hee and Kim Yo Han, made its official debut by releasing its first mini-album, "Emergency: QUANTUM LEAP," on Aug. 27.
