As Yang Lu said, actors should keep some distance from the audience and not leave a stereotypical impression.
But Ding Shan's situation was unique. No one wanted to get rid of her previous weak and cute image more than Ding Shan. Little angels and peaches in the world were not Ding Shan's original personality, and she was forced out of her silence by Ding Wan and Yang Hua. She only knew how to nod and smile like a puppet and did not dare to say a word.
Ding Shan needed the most now an opportunity to show herself and use the most direct method to leave a different memory in the audience's hearts.
Variety was the best way. Whether or not she could leave an impression in the audience's hearts that 'So this is what Ding Shan is like' depended on this one move.
This was also a good breakthrough for Ding Shan's future acting path.
