P'ang Yun (740-808) was a well known Chinese Zen Layman.
He was once selling bamboo baskets. Coming down off the a bridge, he stumbled and fell.
When Ling-chao saw this she ran to her father's side and threw herself down.
A nation is like a hierarchy, a marketplace, and a maiden.
A maiden wins her husband by submitting to his advances;
Submission is a means of union.
So when a large country submits to a small country
It will adopt the small country;
When a small country submits to a large country
It will be adopted by the large country;
The one submits and adopts;
The other submits and is adopted.
