The moral of this story is that we should be cautious about making assumptions. The farmer assumed the crane was helping, but it was only after its own interests. We often do the same in life and end up being wrong about people's motives.
The moral is to be considerate of others' differences.
Well, in the 'farmer and the crane' story. There was this farmer busy at work in his field. The crane would show up. As the farmer plowed, the crane took advantage of the situation to find food like frogs that got exposed. The farmer, seeing the crane around all the time, wrongly assumed it was there to assist him in farming. Eventually, when he caught the crane, the crane pointed out the truth. So, it shows that we should be careful about making assumptions about others' motives based on appearances.
The moral could be about kindness and its rewards. The old couple showed kindness to the crane, and in return, they received some benefits.
The moral is about treating others as you would like to be treated. The fox was inconsiderate when he served food in a way that was easy for him but difficult for the crane. Then, when the crane reciprocated with a meal served in a way that suited him but not the fox, the fox learned a hard lesson.
The moral could be that everyone, regardless of their social status, has something valuable to offer. The farmer, though simple, might have wisdom or qualities that the king lacks.
The moral could be that true beauty lies not in outward showiness but in inner qualities. The peacock was all about its flashy feathers but might have been lacking in other important aspects, while the crane had its own simple charm.
Well, in the 'woodcutter and his wife crane story', the moral is related to not being overly greedy. The woodcutter was happy with the crane's help at first. However, his wife's excessive curiosity and greed to know more and get more led to the crane leaving. So it tells us that being greedy often results in losing the good fortune we already have.
The moral might be about acceptance. The crane and viper are so different, yet if they are in love, it means they have to accept each other's ways. The crane has to accept the viper's ground - dwelling and often solitary nature, and the viper has to accept the crane's aerial and more social side. It's a lesson in embracing differences in a relationship.
The moral could be the value of experience and wisdom. The old farmer, with his years of living and working on the land, has likely faced many situations. His decisions are probably based on all that he has learned over time.
The moral is probably 'Greed leads to downfall'.
