BEIJING – Karaoke singers in Beijing are being forced to listen to an anti-drugs song before belting out tunes as part of a crackdown on narcotics use ahead of China's National Day, state media said Friday.

Police have told more than 1,200 karaoke venues in the capital to install the three-minute "educational video" as authorities clamp down on drug users and dealers ahead of the October 1 festivities, the Global Times reported.

"It pops up after you start the system. You can't cut it short but have to wait till the song finishes," said Li Tong, manager of a Party World karaoke venue.

"Some sing to it. The tunes are quite catchy."

China is planning a military parade, mass song and dance performances, and fireworks on October 1 to mark the day when revolutionary leader Mao Zedong proclaimed the founding of Communist China in 1949 at Tiananmen Square.

Authorities have started clamping down ahead of the celebrations, with thousands of additional police already deployed in the capital.
