The idol weekly ranking site "Fan & Star" on Wednesday carried out a surprise project for Choi Bo-min. It is a large advertising project to celebrate Choi Bo-min's birthday on April 24.

Choi Bo-min's birthday event is a support project in which success is determined by the number of stars (points that fans can gather on the site) donated. The more stars are donated, the more advertisements for Choi Bo-min's birthday are posted throughout Seoul.

If 50,000 stars are gathered, a congratulatory video will be displayed on the CM board (square column) of Hapjeong Station on Subway Line 2. When the number of stars reaches 100,000, a video will also be displayed on SM board (wall) of Gangnam Station, Subway Line No. 2.  

Once 200,000 stars are filled, congratulatory videos will also be shown on the electronic display board of the waiting room at 43 stations on Subway Line 2. In addition, special gifts such as Apgujeong CGV Screen, Hongdae Station Multivision and Travel Bus Advertisement await fans.

Choi Bo-min's birthday support will run through April 11, and she can participate in the "Star Market" section on the "Fan & Star" website.
