Coronavirus: Chinese school gives pupils a hat tip to teach them how to keep their distance

Description

One legend says that the first Song emperor ordered his ministers to wear hats with two long wings on the sides so that they could not chitchat in court assemblies without being overheard, according to Tsui Lik-hang, a historian at City University of Hong Kong.

However, he warned that this story came from a much later source, adding: “The Song emperors, in fact, were also depicted to have worn this kind of headwear with wing-like flaps.”
