Young people don't know the taste of sadness, and they love to go up to the upper floors. I'm not sure if I'm going to be able to do that. In order to give a new word for sadness.

And now I know all the sadness, and I want to talk about it. I'm not sure if I'm going to be able to do that, but I'm going to be able to do it. I'm not sure if I'm going to be able to do it, but I'm going to be able to do it.

Translation:

When people were young, they did not know the taste of sorrow, they liked to climb high and look far and wide, they liked to climb high and look far and wide, and they reluctantly spoke of sorrow for the sake of writing a new word without sorrow. Now tasted the taste of sorrow, want to say but can not say. I want to say but can't say. But said a good cool fall ah!
