Executive production assistant Su Wan joined the crew of "Chang'an's Lost Dream" and encountered chaos such as "Tang Dynasty costumes with Song Ruskirts" and "Modern dance in the palace" for the first time. She revised the script based on historical research, designed Tang's makeup, and dealt with the quality-seeking director Lu Chengyu and the profit-seeking producer Zhang Manni. In the quarrels and perseverance on the set, she not only protected the original intention of "conscience drama", but also gained career growth and secret heartbeat.
