Origin of Chinese Parable: Devils and Righteous Man Can anyone point to the origin of this Chinese parable?

“A man travelling through the country came to a large city, very rich and splendid; he looked at it and said to his guide, ‘This must be a very righteous people, for I can only see but one little devil in this great city.’ 

“The guide replied, ‘You do not understand, sir. This city is so perfectly given up to wickedness … that it requires but one devil to keep them all in subjection.’ 

“Travelling on a little farther, he came to a rugged path and saw an old man trying to get up the hill side, surrounded by seven great, big, coarse-looking devils. 

“ ‘Why,’ says the traveller, ‘this must be a tremendously wicked old man! See how many devils there are around him!’ 

“ ‘This,’ replied the guide, ‘is the only righteous man in the country; and there are seven of the biggest devils trying to turn him out of his path, and they all cannot do it.’ ”
claiming this parable has chinese origin is doubtful. several themes in the text are very un-chinese, against the customs &amp; culture:

1　"travelling through the country"

2　such travelling with a guide

3　seven

in other cultures, 7 might be a "magic" number, but it's not in chinese. we used 5, 10, 12, 3, or 4.

lastly, here's a link of its mormon origin:
