Biniang is a county-level district under the jurisdiction of Hangzhou city, in Zhejiang, a province of the People’s Republic of China. It is across the Qiantang River from West Lake and the older parts of Hangzhou. Like Pudong in Shanghai, it a very modern, and rapidly developing, area that was mostly farmland until ten years ago.
The Qiantang River and the Hangzhou Bay are known for the world’s largest tidal bore. The oldest known tide table (AD 1056) is for the Qiantang River and may have aided ancient tourists wishing to see the famous tidal bore. The tide rushing into the river mouth from the bay causes a bore which can reach up to 9 metres (30 ft) in height, and travel at up to 40 km per hour (25 miles an hour). Known locally as the Silver (or Black) Dragon, the wave sweeps past Hangzhou, menacing shipping in the harbor.
Like Pudong in Shanghai, it a very modern, and rapidly developing, area that was mostly farmland until ten years ago. The district’s total area is 73 square kilometers。
