● Some RMB notes to spend as you arrive in China.
● Electrical adaptors (voltage in China is 220V/50Hz, two or three flat pin plugs).
● Medical supplies like prescription medication, over-the-counter medicine and vitamins.
● Small gifts from your country to give new friends.
● Some of your favorite local snacks and spices to cook when you feel homesick. As big supermarkets have an imported products section providing pasta, cheese, biscuits etc, you'll be able to find common food supplies but probably at a higher price.
