HA NOI (VNS) — A latest documentary on the biggest cave known in the world—Son Doong—located in the central province of Quang Binh, will be broadcast on VTV1 on February 14.

The documentary will feature magnificent scenes from inside the cave that still carry ancient traces of animal and plant drawings, as well as of the people, who made the great contribution of discovering the caves and protecting them.

The scenes from the cave were filmed with Beethoven's Symphony No 5 being played by a symphony orchestra inside the cave at the same time.

Ban Hoa Tau Son Doong (Son Doong Symphony) is the second documentary of its kind and will be broadcast at 8.10pm on Saturday, on VTV1, as part of a weekly VTV Special documentary series.

The documentary series has focused on various subjects, including the fate of the victims of the mysterious flight MH370, that of mixed-blood children given birth by Vietnamese women and fathered by American soldiers after the American war in Viet Nam, and the global impact of the Independent Declaration read by President Ho Chi Minh in Ha Noi on September 2, 1945.—- VNS
