"Have you already been tested today ?"
Have you eaten? 你吃了吗？When you are living in Beijing (or other places in China), you would certainly come across this sentence as a greeting when meeting people. It does not actually mean an invitation for dinner but an informal invitation for small talk or asking how are you are doing.
This picture is now thriving on Chinese social media, especially in Beijing with the new coronavirus outbreak. It is not anymore asking “Have you eaten ?” when meeting people but asking “Have you already been tested today ?” to show care for our mutual well-being and health and the start for a small talk 😊
