Starting from December, the CCAC specially launched the promotional video clip series entitled “Know More about Administrative Complaints” to introduce to the citizens about the purposes of the ombudsman’s functions of the CCAC and its scope of application. The video clips are broadcast in different electronic media including CCAC’s relevant external service offices and bus compartments so as to teach the public how to optimise the use of the complaint system to resolve problems and encourage them to properly understand the practical functions of the CCAC as a watchdog in the ombudsman’s work.
