CETV 4
CETV Channel 4,formerly Air-classroom Channel, a welfare satellite channel covering the whole nation, focused on primary and secondary schools, teachers and parents and provides documentaries.
Since 2003, Air Class Channel played an important role in resumption of school classes in events like ‘SARS’, ‘Wenchuan Earthquake’, ‘Yushu Earthquake’. On December 11, 2008, the State Administration of Radio Film and Television gave an official reply to approve the air class by CETV.
The Air Class Channel was revised in January 1, 2012 by combining the documentaries and textbooks.
