First of all, He Lin's role in Breakthrough is called Tong Gehua. Tong and Lin have been husband and wife for many years, and Tong loves his son so much that his son is lawless. In the process of getting along with Lin, Tong can always suppress Lin's anger, so from a human point of view, Tong should be a gentle female image.
In terms of appearance and temperament, He Lin has a high degree of matching with the role of Tong, but I don't know why He Lin's face looks so strange and often appears. Humiliated? The movements and the position of the mouth also look strange, which leads the audience to think that there is some drama.
Secondly, as far as He Lin's acting skills are concerned, there are some serious problems. He Lin's lines are awkward, probably because he wants to present a gentle temperament, so he speaks a little? With what? Some lines can't even be heard clearly, and the vague voice makes the audience feel very dramatic. It seems that acting also needs more exercise. The consequence of not acting for a long time is that, like He Lin, his acting skills have regressed.
Finally, fortunately, Tong is a supporting role, and Breakthrough is an out-and-out bad film in the eyes of the audience. Even if the audience doesn't like the role of children, they won't give it low marks. After all, "Breakthrough" has no room for retrogression, and more and more viewers abandon the drama.
