Doing the usual in Beijing: drink yoghurt (suan nai/ 酸奶). 7 years ago it was 5 kuai, now its 10 kuai. Today we can pay with WeChat (it’s like our Whatsapp).
There’s even QR code hung at every stall at the wet market. You don’t have to pay cash to your butcher/vegetable seller if you have your phone.
I’m so impress with China – they’ve progressed so much…and we have not.
