Actor Park Hae-jin is joining a campaign to fight against micro-dust with his fans.

The actor made a pledge to plant trees to his fans during an event for a cable TV program last year.

Park’s Chinese fans had donated 520 trees to combat desertification in western China and the actor added 6,000 trees to the donation. During a press conference for the cable TV show, Park promised his fans that he would plant the donated trees with them if the new show reaches 10% in viewership.

Park rose to fame in China for his role in the 2011 Chinese drama "Qian Duo Duo Get Married," which became a nationwide sensation.
