3. SOUNDBITE (English) Gillian Lee, secondary school student:
"There is a class boycott in our school today, and we boycott the opening ceremony of our school year. We first arranged a sit-in in the basketball court, but because of the weather situation, we moved into the chapel provided by school."
4. SOUNDBITE (Cantonese) Andy Chan, secondary school student:
"About the class boycott, I think I would go ahead with a class boycott at school, because I think that secondary school students are part of society, and if we secondary school students decide to boycott classes, that shows that part of society has already stopped functioning. The ultimate aim is to insist that the Hong Kong government responds to our five main demands."
5. Cutaway of masked students at rally
6. SOUNDBITE (English) Isaac Cheng, rally organiser:
"Today is a secondary school students' strike, and we are urging the government to respond to the five demands that the protesters asked for. Especially, you can see the violence of the police yesterday towards the Hong Kong protesters, and the strict sense for the Hong Kong government for not responding to the five demands."

Tens of thousands of students in Hong Kong boycotted the first day of classes Monday as part of a citywide strike following a violent weekend of demonstrations.
Hundreds of secondary school students gathered for a rally in downtown Central district of Hong Kong, added gas masks, goggles and hard hats to their traditional uniforms.
University pupils crowded into a square at the Chinese University of Hong Kong, while workers also participated in their own rally at a public park, braving strong winds and storm clouds as a typhoon threatened.
Nearly three months of youth-dominated protests - calling for democracy and an independent inquiry into police conduct - will be tested as classes resume with the end of the summer break in the semiautonomous Chinese territory.
The young protesters strove to demonstrate their continued determination with Monday's school boycott, the first of a planned two-day strike.
The president of the Chinese University of Hong Kong's student union said 30,000 students attended a rally on campus.
Separately, high school students who were skipping class rallied in Edinburgh Place, a public square in Hong Kong's central business district.
The protesters' demands include dropping charges against more than 1,000 people who have been arrested and formally withdrawing an extradition bill that would allow Hong Kong residents to be sent to mainland China to stand trial.
The appeals are undergirded by a sense among some Hong Kong residents that the Communist Party-ruled mainland government has been eroding the autonomy and civil liberties promised when the former British colony was returned to China in 1997.
