"Pudong"—literally "The East Bank of the Huangpu River"—originally referred only to the less-developed land across from Shanghai's Old City and foreign concessions. The area was mainly farmland and only slowly developed, with warehouses and wharfs near the shore administered by the districts of Puxi on the west bank: Huangpu, Yangpu, and Nanshi. Pudong was originally established as a county in 1958 until 1961 which the county was split among Huangpu, Yangpu, Nanshi, Wusong and Chuansha County. On October 1, 1992 the original area of Pudong County and Chuansha County merged and established Pudong New Area.
