On the first day of China's National Security Law for Hong Kong, 370 of Hong Kong citizens were arrested at the protests.
The Hong Kong Security Law contained the contents of prohibiting and punishing foreign forces and collusions, national division, overthrowing the government, and acts of terrorism, and establishing an agency to implement them in Hong Kong.
The youngest of those arrested was a 15-year-old girl, waving the flag with the message of'Hong Kong Independence'.
The rest of the people were arrested for illegal gatherings, public turmoil, and possession of offensive weapons.
SCMP said, "The scope and target of the Hong Kong Security Law is so broad that it is questioned whether it is feasible in reality."
