The Chinese web series "The Longest Day in Chang'an" has been discussed on various social media platforms since it was launched on Youku, a Chinese video platform last month.

Many viewers mentioned in the comments one of the highlights of the series is its accurate reproduction of Tang Dynasty elements. From the street plan of Chang'an to the costumes of ordinary people in the Tang Dynasty (618-907), the details of this series are commendable.

To more accurately understand the situation in the art design of this series, CGTN interviewed one of the art directors of the series, Jin Yang, who shares his views about the role of art design in film and television plays, as well as some problems encountered in the art design of this series.
