Han Han's choice of the female lead for the movie " Triple Door " was very important. The main characters in Triple Door included the male lead Yin Tianzhao, the female lead Mei Ting, and the supporting role Lin Yichen. If you want to choose the most suitable female lead, I think it should be Lin Yichen. Lin Yichen was an outstanding actress who had starred in many movies. Her fresh and natural image was very consistent with the characters in the novel, and it could well interpret the growth process of the heroine in the novel. In addition, Lin Yichen's acting skills were also very mature, and she was able to interpret the complex emotional scenes in the movie very well, adding a lot of color to the movie. Other than Lin Yichen, the other female leads could also be chosen based on the characteristics of the characters in the novel. For example, Mei Ting's strong image could well interpret the character change of the male protagonist Yin Tianzhao in the novel, and Yin Tianzhao and Lin Yichen had a deep emotional connection, so they could choose the female protagonist with emotions as the main line. Choosing the most suitable female lead was very important to the filming effect of the movie. He hoped that the movie could be presented in the best state.
