Tao Te Ching Chapter 61
A big country (should be like) the delta low-regions,
Being the concourse of the world,
(And) the Female of the world.
The Female overcomes the Male by quietude,
And achieves the lowly position by quietude.
Therefore if a big country places itself below a small country
It absorbs the small country.
(And) if a small country places itself below a big country,
It absorbs the big country.
Therefore some place themselves low to absorb (others),
Some are (naturally) low and absorb (others).
What a big country wants is but to shelter others,
And what a small country wants is but to be able to come in and be sheltered.
Thus (considering) that both may have what they want,
A big country ought to place itself low.
