When I was in working and living Shanghai, this was one of my favourite food to eat at a local shop on the main road outside my compound: wonton with pork fillings in a soup. It costed about RMB 5 or about USD 0.80. It’s a simple and delicious dish and is also light on your stomach. You eat the wontons and drink the soup and you don’t have to buy a seperate beverage. Very practical.
