Introduction to the Ocean Theater of My Dream: As the Olympic Sailing Center Grand Theater is about to be completed, the theater invites children in Qingdao to hold a painting collection activity for the "Ocean Theater of My Dream". The event invited 89 children to paint on the spot in the theater, using their brushes to depict the Ocean Theater of their dreams. These works were assembled into a 100-meter scroll, which was displayed before the theater's first performance. It was of profound significance.
