写一小段介绍上海的英文

问题解答：

Shanghai is China's most comprehensive industrial and commercial city, ranking the first in population and population density. As a tourist city, it attracts travelers from both home and abroad by its commercial activity rather than scenic beauty.
Shanghai is situated on the bank of the Yangtze River Delta, with East River in the east and Hangzhou delta in the south. Housing a population of over 16 million at present, it was once a small town supported by fishing and weaving before the first Opium War. Late in 1990, the central government started developing the area, and has since became the well-known booming metropolis city.
Dressing in Shanghai is casual but modest. Bring along some heavy clothing for the winter whereas light clothing is adequate during summer.
Visitors to China are required to fill in a health declaration form at the Customs. Medical facilities are generally adequate in Shanghai. It is advisable to drink only boiled and bottled water
