There is a restaurant in Yiwu, China which operates almost non-stop. The regular customers couldn’t help but notice the incredibly hard-working couple running the place. They seemed to be working without any rest whatsoever from 6am till 3am. The locals even gave the untiring couple the nickname “Robot Couple”.
But as almost all mysteries have a logical explanation so does this one. The Chinese couple was actually a quartet of two couples of identical twins. The twin brothers aged 32 managed to find a set of twin sisters and eventually married them. It turned out that the non-stop restaurant was run by two couples of identical twins who took shifts. It’s also worth mentioning that both couples have sons who are almost identical as well.
The couples love working together in the restaurant because it enables them to live together like one big family. They are also quite fond of the robot nickname as it describes their incredibly busy lives.
