Six buses decorated with ocean-themed 3D paintings debuted in Yantai, East China’s Shandong province on Aug 23, 2015. To provide a warm and comfortable environment for the passengers, Yantai Public Traffic Group Co. Ltd. hired a professional team to paint the six buses, turning them into 3D "aquariums".
