Local residents pose for a picture on a marine surveillance ship Tuesday. The open house on the surveillance ship was held to mark World Ocean Day, which falls on Saturday. Carrying 120 residents, the ship passed through Shenzhen Bay Bridge, Shekou Cruise Homeport and Dachan Island, allowing residents to view the beautiful scenery in the waters off western Shenzhen while learning about the ship’s structure and function. In the following week, more activities will be held, such as the release of fish fry and popularization of marine animal science. Xu Qiang
