Known as the “Paris of the East” and competing with Hong Kong to be known as the "Pearl of the Orient," expats moving to Shanghai will find themselves in a metropolis shaped by local and international influences. By some measures the largest city in the world, Shanghai welcomes the world from its position on the estuary of the Yangtze River, and boasts one of the largest ports in the world.

Cost of Living: 
Cost of Food in Shanghai: The great thing about buying groceries in Shanghai is that just about anything can be found at foreign supermarkets like City Shop. Imported produce is, however, more expensive than back home. Expats who would like to live cheaply can "rough it" like many locals and foreign students do by eating at a small mian guan or tan restaurant for dinner. Slightly more mid-range Chinese-style restaurants would usually cost more per person.
Transport and Driving:   (MTR) (TAXI) (BUS) transportation costs can be kept to a minimum for someone based in
big city like Beijing, Shanghai or Guangzhou, which have reliable and affordable public transit systems. Many other people choose to cycle or ride scooters, which is often the easiest and cheapest way to travel short distances in Shanghai.

Accommodation in Shanghai is varied, with old and luxurious homes pressing against new high-rise developments and suburban neighborhoods. Exploding outwards, much of Shanghai’s growth has taken place in the last two decades, with developments becoming newer the farther one travels from the city Centre. With the Huangpu River running vertically through its centre, Shanghai is split into two regions - Pudong, east of the river, and the older downtown area to the west. Generally, expats find housing in a wide horizontal stretch through the centre of the city in both regions.

Taxation: Resident companies are taxed on their world incomes and the nonresident companies on the Chinese incomes.
