The innermost bay of the Yellow Sea is called Bohai Sea (previously Pechili Bay or Zhili Bay). Into it flows both Huang He (through the Shandong province and its capital Jinan) and Hai He (through Beijing and Tianjin).
The Korea Bay, between the Chinese Liaoning province and northwestern North Korea is also part of the Yellow Sea.
The Bohai Sea and the Korea Bay are separated by the Liaodong Peninsula, with Dalian at its southernmost point.
