Can’t read Chinese, but assume that relates to China’s inability to comprehend our divided government.
it is a common proverb with multiple layers of meaning.
a loose literal translation is
under the sky, we are all one family.
or
we all live under a common sky.
in china, under the sky can denote either the universe, or the world, or the legal dominion of the chinese government. one family can mean either we look out for each other, or that we all need to live cooperatively for the common good.
alternately, in ST-ese, “you will be assimilated. resistance is futile.”
haha
