It's the first week of school, but there's one problem -- thousands of students are missing from the classrooms.
At 10 of the city's 13 universities, students are staging a class boycott, and student union leaders estimate that more than 100 secondary schools also planned class strikes.
It's the latest move in pro-democracy protests
that have rocked Hong Kong for the past three months, and the students say it will continue until the government responds to all of their five core demands. So far, Hong Kong Chief Executive Carrie Lam has acquiesced to one: the full withdrawal of the bill that would have allowed extradition to mainland China, and which sparked the protests in June.
While the demonstrations have spanned all demographics, young people have become the face of the movement, and some have been at the most violent, extreme end of the clashes. More than 1,100 protesters have been arrested this summer -- one 13-year-old was arrested for being in possession of two petrol bombs, police say.
Now students are going through the motions of starting a new school year, buying books and registering for classes. It's a familiar routine, but nothing about it feels normal.
"The city is dying," said Kris Fan, a 17-year-old high-school student. "We can't just sit here and read our books. That's no use. I think the city is more important than our academics."
After a summer holiday defined by tear gas, political activism, and the worst political crisis Hong Kong has seen in decades, many young people say they simply can't return to normal student life.
One summer can change everything
When 21-year-old Davin Kenneth Wong watched the science fiction television show "Stranger Things" with his friends last month, he was struck by its parallels with his own life.
In the Netflix show, a band of rebellious kids (plus one with superpowers) do battle against otherworldly monsters to save their hometown. "One summer can change everything," the trailer said.
"We totally feel that," said Wong, president of Hong Kong University's Student Union (HKUSU). "This summer really changed everything. We were fighting real-life 'Stranger Things' -- but instead of fighting something from another dimension, we're fighting the police."
Usually, students spend their summers hanging out with their friends, going to the beach, and resting up. Instead, this summer they transformed into seasoned protest veterans, strapping on gas masks and hard hats.
Student unions helped from the sidelines, encouraging students to attend large rallies. Hong Kong University's union also engaged lawyers to provide assistance to arrested students, Wong said. Law students offered protesters legal advice, and medical undergrads volunteered as frontline medics.
In some ways, we've seen this before -- student activism has a long history in Hong Kong.
In 1989, thousands
of the city's college and high school students staged rallies to support students protesting in Beijing's Tiananmen Square before the crackdown. The Hong Kong Federation of Students, a cross-college students' union, held fundraisers in support of their mainland counterparts' fight for democracy.
Students struck again in 2003 and 2012, blocking legislation they felt gave Beijing too much power. But Hong Kong's young people were truly catapulted onto the global stage during the 2014 Umbrella Revolution. Protest figureheads like Joshua Wong, then just 17 years old, were depicted worldwide as teenage revolutionaries.
The 2014 movement ultimately failed, with the electoral system remaining uchanged. Some of its most high-profile figures, including former student leaders Nathan Law and Sixtus "Baggio" Leung, ran for office and won legislative seats -- but they were disqualified in a heated controversy
The tensions of that failed movement have reemerged this summer -- but this time, the students have learned from the lessons of 2014. There is no central figure with star power. Their movement is leaderless, fluid, and democratic, as well as darker and more nihilistic.
Protesters began masking their faces as the violence ramped up this summer. Recent weeks have seen young people setting large fires in the street and throwing petrol bombs at riot police, who respond with tear gas, rubber bullets and water cannons.
The escalation in violence stems from feelings of desperation, as Hong Kong's young people feel like time is running out in their fight for democracy. The semi-autonomous city currently enjoys certain freedoms and its own legal system under an agreement between former colonial power Britain and China. That 1997 deal ends in 2047, when Hong Kong will be likely absorbed into Xi Jinping's authoritarian China.
The fear around that deadline is evident in the protesters' rhetoric. Posters around the city and on campuses read, "If we burn, you burn with us," and "Give me democracy or give me death."
"We're losing," said Fan. "We're losing things like freedom of press, freedom without fear. We're just fighting for what we have now."
