2 things: Great Xiamen food and Cashless payment everywhere we went. Our director took us to all the best food places in Xiamen and I was surprised to find all these Singaporean food that originated in Xiamen i.e. Beef Hor Fun, Oyster Omelette, etc. Got some rice dumplings (Ba Zhang) off a roadside vendor too. And they paid cashless. 微信 style! Everywhere! I was the only one offering to pay in cash like it was yesterday's thing to do! Everyone from the young supermarket cashier to the older roadside fruit stall vendor who hardly spoke any English did WeChat payment. I haven't seen a local use a single bank note throughout my entire time here!
