Is Jinghai Building still considered a navy?

Forget it. According to a search on Zhiyouji.com, Jinghai Building is a unit directly under the Naval Command of the Chinese People's Liberation Army. The building is constructed and managed according to four-star standards and is positioned as a business conference hotel. It is now the navy's highest-level reception hotel, responsible for large-scale receptions within the military, local governments, agencies and various social groups. Jinghai has won many honors for its high-quality products, excellent services and beautiful environment, and was awarded the Five-Diamond National Premium Restaurant by the China Hotel Association.
