Weihai.

Weihai, formerly Weihaiwei, is a prefecture-level city and seaport in easternmost Shandong, bordering Yantai to the west and the Yellow Sea to the east; it is the closest mainland Chinese city to South Korea. Its population was 2,906,548 at the 2020 census. Weihaiwei became a military stronghold in 1398 against pirate raids, and the fortification was constructed in 1403 with walls almost 3.2 kilometres in circumference. The Japanese occupied it in 1895 and returned it to China on 24 May 1898, after which it was occupied by the British. The core of the city, now Huancui District, was ruled by the British from 1 July 1898 to 1930, with Port Edward as its capital and a Royal Navy base on Liugong Island. Weihai became a prefecture-level city of its own on 15 June 1987.
