Protesters in Hong Kong have annnounced a new dress code in anticipation of demonstrations on National Day: tuck your shirt in.
The messages, widely circulated on social media and encrypted platforms such as Telegram, claim such a fashion choice would make it harder for undercover police to hide revolvers or batons.
One officer, thought to have been undercover, fired a live round into the air in warning during clashes in Wan Chai on Sunday afternoon.
Police have not confirmed that the officer – whose face was wrapped in coverings similar to that of the protesters – was on an undercover mission, merely saying he fired the shot to protect the safety of his colleagues, who were “surrounded and attacked” by protesters.
“You think it’s too nerdy to tuck your shirts in? It could probably save your life!” one post on the Reddit-like site LIHKG read.
“Everyone, tuck your shirt in on October 1 so the gun-carrying spies can be spotted.”
The protesters have drawn inspiration from the “Four Heavenly Kings of Canto-pop” – Leon Lai Ming, Aaron Kwok Fu-shing, Jacky Cheung Hok-yau and Andy Lau Tak-wah – by reproducing a picture taken in the 1990s in which the four singers had all tucked their shirts in.
Others called for further caution and suggested rolling up trousers too, fearing officers could hide revolvers around their ankles.
Other measures being adopted by protesters included setting a scheduled message to reveal their name, age, ID card number and a warning they might have been arrested if they have not returned by a certain time.
