What can be shown, cannot be said.

【译文】不要笑话别人很老，自己有一天也会变老。同邻里相处好，就像捡到一块宝贝一样可贵。只要安分守己做人，一生都不会有烦恼。

"The colony is the place where the project of a new humanity is to be tested, where the dream of a world without borders is to be realized, where the dream of a world without races is to be realized, where the dream of a world without nations is to be realized, where the dream of a world without classes is to be realized, where the dream of a world without genders is to be realized."

Don't let anyone tell you that you can't do something.
