At the airport
In China's airports, you will easily spot these drinking water machines which are scattered around for people to get free water - a selection of cold, warm and hot (boiling) options. It's really convenient. That's also the Chinese culture of drinking warm water, whereas in western airports this service is hardly available - you have to buy either coffee or tea.
The last hour in China - taking off at midnight. Hope everything goes well and will be back to UK hours again soon.
