The village of Kwan-Si built the wall surrounding their village in the shape of a pig.
A close village had their walls built like an orange. They will be eaten by the pig, so travelers will go to the pig shaped village.
The city changed their walls from being an orange to a club, to beat the pig and drive it off.
The city of Kwan-Si, hearing of the the new wall, built their wall like a great bonfire. To burn the club.
The city then built their walls to resemble a shining lake, to put out the bonfire.
The city of Kwan-Si then builds their walls to resemble a mouth. The mouth would drink all of the lake water.
Then the other city built their walls like a needle, to sew the mouth closed.
The city of Kwan-Si built their walls to resemble a sword, to break the needle.
The other city built their wall like a scabbard, to sheath the sword.
The city of Kwan-Si builds their walls like lightning, to destroy the scabbard.
They finally come together to put an end to the endless building. The city of Kwan-Si is made into wind, And the other city is made into a kite. These two things give each other purpose.
