Avoid the Rush Hour
In China's big cities, such as Beijing, Shanghai and Guangzhou, the traffic is bad during rush hours due to the mass movement of large populations, so tourists are advised to avoid the peak hours between 7-8 AM and 5-6 PM. This will make for an easier and more pleasant journey.
Power Supply
China uses 220 volt power supply for standard domestic and business purposes. Hotels generally provide wall sockets in every bathroom for razors and hair dryers, accommodating both "straight two-pin plugs," and "triangular 3-pins plugs."
Water
In China, tap water is considered quite hard and needs to be boiled before drinking. Therefore, Tap water at all hotels in China is not drinkable. Inquire with hotel staff members when you check in. If you are unsure it is recommended you drink bottled water only or cool boiled water offered by hotels.
