Actress Ha Yeon Soo joined the yellow ribbon campaign.

Yesterday, Ha Yeon Soo posted on her Facebook, "One's small act for a big miracle. I heard the meaning of forsythias is hope" along with a picture.

In the picture, praying hands are shown with a yellow ribbon around the wrist. Below the hands are forsythias.

A student organization decided to start the yellow ribbon campaign in hopes of the safe return of those missing in the ferry, getting the idea from yellow ribbons that were tied to trees when American soldiers went out to war in the past.
