Alexandra Wong, a protester known as Grandma Wong who attended rallies over the course of Hong Kong's unrest last year, holds a U.K. national flag, also known as the Union Jack, while waiting to enter the West Kowloon Magistrates' Courts ahead of a hearing for 47 opposition activists charged with violating the city's national security law in Hong Kong, China, on Monday, March 1, 2021. Hong Kong police charged dozens of opposition activists including Joshua Wong with conspiracy to commit subversion, taking formal action against them less than a week before China's highest-profile annual political meeting.
