There is nice popular drink in Beijing – ‘SuanNai’, a kind of liquid yogurt wich I think is traditionally from Inner Mongolia. It comes in a nice, recyclable clay pot. You drink it on the spot with a little straw, then leave the pot on the shop counter.
You don’t always have to drink it on the go. I’ve seen people having it around a nice table, in the shade. Chatting around it.
Interesting, I found, how the pots were not immediately taken away, but kept on the counter or the table. It’s actually quite appealing, in a way: if so many people have enjoyed a pot of Suan Nai, I should have one too!
This is also some sort of smart ecological thinking: recycling the empty container; using it as a marketing tool, meanwhile.
