Students from 10 Hong Kong universities and more than 100 secondary schools join a class boycott on Monday, with warning that they will escalate the action if the government fails to meet protesters’ demands related to the extradition bill by September 13.
The 10 colleges and universities include The University of Hong Kong, Chinese University of Hong Kong (CUHK), City University, Polytechnic University, Baptist University, Lingnan University, The Education University, Shu Yan University and Hang Seng University. They demand that the Carrie Lam government respond to the “5 major demands” of Hong Kong people.
At 3:30 pm, the main quad at Chinese University was flooded with students, undaunted by No. 1 strong wind, yellow thunderstorm warning and occasional heavy rain. Numerous people are arriving with an estimated over 100,000 in attendence.
