There are no moral lessons in this. In fact, this kind of idea challenges our common understanding of appropriate behavior and respect. Morality is about treating others with dignity and equality, and this concept is so far from that, it couldn't possibly hold any positive moral implications.
There are very few positive or common 'licking the old woman's feet stories' in general culture. It's rather an odd and inappropriate concept. However, in some extremely strange folktales from very remote areas, there might be some symbolic actions related to showing extreme respect or penance that could be misconstrued in this way, but these are very rare and not mainstream at all.
Maybe it could be about self - sacrifice in a very odd sense. The act of licking feet is not pleasant, so if a kid does it in a story, it could be seen as sacrificing their own comfort for some greater good, like making amends or showing loyalty. However, this is really stretching it and not a typical moral lesson. In normal children's stories, we have much more straightforward and positive morals like honesty, kindness, and perseverance.
The story of Urashima Taro teaches about the consequences of being away from home for too long. It also gives a sense of the mystery of time. It makes people think about how quickly things can change and how precious the time we have in our familiar world is. It's a warning about the unknown and the importance of cherishing the present.
Another moral is about loyalty. In 'The Generals of the Yang Family', the Yang family members are extremely loyal to their country. They fight bravely against the invaders even at the cost of their lives. This kind of loyalty is highly praised in old Chinese stories.
Another lesson is about trust. Just because there are rumors doesn't mean one should immediately jump to conclusions. But at the same time, if there are signs of unfaithfulness, it's important to address them. For example, in some stories, the husbands ignored the signs until it was too late.
In 'Beauty and the Beast', the moral is that we should not judge people by their appearance. Beauty sees the good in the Beast despite his hideous form.
Stories such as 'Kong Rong Gives Away Bigger Pears' teach the value of self - lessness and respect for others. Kong Rong, at a young age, was willing to give the bigger pears to his elders and siblings, which sets an example of good moral behavior.
In 'The Tortoise and the Hare', the moral is that consistency and perseverance are more important than natural talent. Just like the slow - moving tortoise wins over the overconfident hare.
In old Islamic stories, a common moral is the importance of kindness. For example, many stories show how helping the poor and the needy is highly regarded in Islam. It's a direct teaching of how we should behave towards others.
In Punjabi old stories like Heer Ranjha, one moral lesson is the importance of staying true to your love, no matter how difficult the circumstances. Their love defied family and caste norms, teaching us that love can be a powerful force that should not be easily given up on.
