How did Irene Wan's version of da ji change from a little girl to a fox?

Da ji was calculated as an uber. The king couldn't be with her, but he still wanted to be with her. It was useless for his ministers to stop her. Later, the king wanted to spoil her, and there was a fire in the palace. The king also thought she was a demon, so he put her in the cold. Later, her life was so sad that everyone alienated her. Once, her little dog (Xiao Queqi) ran to another concubine's room, and the concubine also stewed Xiao Queqi for da ji to eat. Then those people provoked her and deliberately showed her how happy her sister was, saying that her sister had left her alone. Later, she was sent to the place where the crazy concubine lived, which scared her half to death. A eunuch tried to take her away, but she didn't seem to run away. She was so scared that a demon appeared and offered to help her, so da ji became a fox.

Drama Review: The List of Gods was originally a novel with strong plot, but in the hands of Hong Kong filmmakers, its style changed greatly. A lot of action, funny and other entertainment elements are added, which reminds people of the Journey to the West, which is also shot wirelessly. Among them, Nezha, played by Chen Musheng, is a born rebel who lives on an ancient "juvenile problem". Various things happen frequently between him and his mother, friends and lovers, and the exaggerated fighting from beginning to end makes this version almost a funny drama. In this version, the most popular is da ji, who was reduced to a supporting role and played by Irene Wan. His costume is amazing and his performance is in place. (Sina Entertainment Review)

This version has greatly changed the plot. Da ji, played by the Irene Wan version, is full of jokes. In this play, Su Daji goes from kindness and madness to hate from love, and then to crazy revenge on his former sweetheart. Therefore, great changes in personality and role need superb acting skills to support, and Irene Wan did it. This version of Irene Wan, introverted, kind and pitiful, is the most authentic, credible and tense. (Netease Review)
