Which province does Zhanshan belong to? Is it a coastal city?

Hello, dear, the beautiful mood team is happy to serve you. 1. It belongs to Guangdong Province. 2. The coastline of Zhanjiang is 1556 km long, accounting for 46% of the coastline of Guangdong Province. Five counties (cities) and four districts all face the sea, including 372km in xuwen county, 0/45.7km in Suixi County, 75km in Lianjiang City, 48km in Wuchuan City and 406km in Leizhou City. There are more than 30 coastal islands (excluding sandbars and reefs) with a total coastline of 780 kilometers. The largest island is Dongdao, with an area of 286 square kilometers and a coastline of 126 kilometers, making it the fifth largest island in China. There are also Nansan Island, Weizhou Island, Dongtoushan Island, Diaoshun Island, Techeng Island and Xinliao Island. If it is useful to parents, I hope to adopt it.
