One umbrella lasted for a long time and the rain stopped. What's the name of this song?

.. friend, it doesn't seem to be a song.

There was an umbrella that lasted for a long time and refused to accept it when the rain stopped; There is a bunch of flowers that have been smelling for a long time, but they still refuse to throw away after withering; There is a friendship that I hope will last forever, even if my hair is blue and white, I can stay in my heart.

It's just a talk about friendship. ..
