Song, when you read this letter, I am already a national first-class protected animal, and if you beat me again, you have to step on the sewing machine. Time flies, it's been hundreds of long years since I left that hill, and now I eat well, sleep well, and don't have to worry about someone beating me in the middle of the night. Oh, and by the way, I also gave birth to a litter of babies and had a chance to introduce you to each other. Song, I miss you, the wind tonight is just as heartwarming as the night when you and I first met, and the only difference is that I will never see you again. The tree wants to be quiet and the wind does not stop, the tiger skin is itchy and loose, I long hope you can come back to see me, even if it is a glance, as long as you come, no matter how far long, I will wait for you.
