Why is it called "Mockingjay"

I forgot when I watched the first two Hunger Games, probably a year or two ago. To this day, I still vaguely remember the storyline, but the names, positions and looks of each protagonist are not very suitable, except for the first female Katniss Evdean (Francis Lawrence). After all, this is the first film I've ever seen of her.
After watching this movie, the feeling may be similar to the first two films. It is really happy to feel that we are living a good life now. Thanks to the Chinese Communist Party for taking care of our healthy growth.
Looking at the scene, the most impressive thing about the whole movie should be that when Katniss Everdeen sang the song "The Hanging Tree", she said that the song is the most moving. Just like at the opening ceremony of the 2008 Beijing Olympic Games, what impressed me the most and moved me the most was when the little girl Lin Miaoke appeared, and the audience quietly listened to the children's voice of "Singing the Motherland". I feel that several scenes and scenes are changed when singing in this film, and the sound of the song does not stop, but is connected to the chorus of the rebels behind. I feel that the revolutionary spirit full of hope is slowly ignited, which makes people feel twice Excited.
There is also a little joke in the whole play that I am amazed by, that is when Katniss Everdeen agreed to be a Mockingjay and made his request to Omar Coyne, at the end Omar Coyne asked Katniss Coyne. When Evdeen asked for anything else, Katniss Evdeen looked down at the small note in her hand, and said weakly: My sister wants to keep her cat. This made me laugh out loud, in love with Katniss Everdeen's cuteness.
The whole movie is down, but as far as the characters in the movie are concerned, I have to admire Omar Coyne (Julianne Moore), who made the plan of resistance, for her careful and accurate planning. After reading it, I can say one word, admiration!
There is also the abrupt ending at the end, which is beyond my expectations. I said in my heart: This...this is gone? The battle I've been waiting for is over? unbelievable. But maybe this ending is to make the audience look forward to the lower part of the final version. Is it really good to split a big battle like this?
I hope I don't forget too much about The Hunger Games 3 (Part 2) when I see it.
