I know of a man, who was digging in his field, he had seen
China on a map and wanted to go there, and by his estimate
China was just under his feet. It was a cumbersome job and
the hole was deep almost hundred feet .... and then its wall
collapsed - in a round hole there is only one wall - he was never
seen again. For many years when someone died in the village
the digger came, it was said that so and so had gone to
China. But wait the story of hopeless travail didn't stop there.
There is a legend in Manchuria of a strange man who suddenly
appeared in a paddy field pointing to the ground looking for
a lost hole, said he wanted to go home which was impossible.
Digging a hole for yourself is not a smart thing to do, because
when you leave the safety of what you once knew there is no
telling what you might find, a gold mine or a rice paddy.
