A man writes a message in front of a Lennon Wall at a pedestårian footbridge in the Sai Wan Ho district of Hong Kong, China, on Friday, July 12, 2019. Lennon Walls -- named after a memorial created in the 1980s in Prague to honor Beatle John Lennon's message of peace -- have appeared in random public spaces, from areas outside train stations, to subway crossings and footbridges. Expressions on brightly-colored stickers adorn the walls, offering support, calling for the withdrawal of the draft legislation and criticizing the police's handling of related protests.
