BEIJING, Jan. 7 (Xinhua) -- Forty-five public service advertisements promoting filial piety stood out in a selection jointly held by the National Radio and Television Administration (NRTA) and the National Committee on Aging.

Covering radio and television advertising as well as graphics, the advertisements have been submitted to a public database of the administration and are now available to radio and television broadcasting institutions across the country, the NRTA said in a circular Tuesday.
