An "Old Tang Book" takes Gao Yangyang through time to the Zhenguan period of the Tang Dynasty. Watch the prosperity of the prosperous times, the coming of thousands of nations, the struggle for power, the pursuit of fame and fortune, the deep love between childhood sweethearts, and the quiet and beautiful Sanskrit sounds of the years. Is it to remain silent or to seize the opportunity? Is it the view from the palace gate, or the sound from the Buddhist temple?
