Hong Kong protesters on Sunday (December 8th) made huge human chains in Causeway Bay while wearing animal masks.

Many wore Pepe the Frog and LIHKG pig masks.

Pepe the Frog has become a symbol of the unrest in Hong Kong, even though it also popular alt-right meme in the USA.

LIHKG pig is another symbol of protest. LIHKG is a forum website similar to Reddit which demonstrators have been using to coordinate their activities.
