How large is Baietan?
"Baietan" can mean a stretch of the Pearl River, the riverfront by Shamian and Huangsha, or a 36 km² planning area.
ONEA stretch of water
South of old Xiguan the Pearl River splits into its front and rear channels; Baietan is the broad, deep water at the fork. Qu Dajun's Guangdong Xinyu records "two li up the Pearl River lies Baietan, wide and deep". The "pool" is a deep channel where visiting merchant ships anchored from the Song dynasty onward. A water name, with no administrative boundary.
TWOA riverside landmark
The riverfront by Shamian Island, the White Swan Hotel and Huangsha pier is also called Baietan. "Moon over the Goose Pool" was named one of the Eight Sights of Guangzhou in 1963, and newer landmarks such as the Baietan Greater Bay Area Art Center and MixC line this stretch. A stretch of riverfront: wider than the water name, narrower than the planning area.
THREEA planning area
The Baietan Area Development Plan (2020–2035), issued in 2021, uses the name for a 36 km² planning area covering much of southern Liwan: Datansha, Shiweitang, Huadiwan, Guanggang, Guangchuan and Dongsha. In reporting, "Baietan business district" refers to this third sense.
