Haikou
capital of Hainan province, China
Haikou is the capital and most populous city of the Chinese province of Hainan. Haikou city is situated on the northern coast of Hainan, by the mouth of the Nandu River. The northern part of the city is on the Haidian Island, which is separated from the main part of Haikou by the Haidian River, a branch of the Nandu. Administratively, Haikou is a prefecture-level city, comprising four districts, and covering 2,280 square kilometres (880 sq mi). There are 2,046,189 inhabitants in the built-up area, all living within the four urban districts of the city.
Haikou was originally a port city, serving as the port for Qiongshan. During the Chinese Civil War, Haikou was one of the last Nationalist strongholds to be taken by the Communists with the Battle of Hainan Island in 1950. Currently, more than half of the island's total trade still goes through Haikou's ports.
The city is home to Hainan University, a comprehensive research university under the Project 211 and the Double First Class University Plan in certain disciplines, which has its main campus on Haidian Island.

Why this record matters
A short description can identify a subject without explaining its stakes. For “Haikou”, the useful work is to connect “capital of Hainan province, China” to the records capable of establishing context and consequence.
The strongest evidence will usually combine a dated visual record with documents produced by the authority responsible for the place. The source revision retrieved here is dated Sep 28, 2026. The linked authority identifier is Q189823. VIAF identifies the subject as 234318094. Authority coordinates are 20.020, 110.320. 2 of 3 selected statements include explicit references; 1 carry qualifiers and 0 use preferred rank. The first chronological checks are 1950.
Architectural summaries often privilege surviving fabric and can understate demolished phases, contested use or displaced communities. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
