Other animated versions of this tale (both also quite good):
Fox and Wolf (1936) - earliest surviving Soviet colour animation - unfortunately, the last 10 minutes didn't survive
Be Caught, Fish (2005) - part of the "Mountain of Gems" series, this one has an irreverent Ukrainian flavour

The wisdom of the fox is a very familiar literary motif in Europe for thousands of years, but in Asia where the fox is hardly a common creature, the only corresponding image is the snake. In Aleksandr Nikolayevich Afanasyev's original, the fox even made the lion breaks the wolf's leg. However, that is a fable, but in my opinion, life forces us to have both the cunning of the fox and the ferocity of the wolf to survive.

Now I will tell a famous folk poem from Northern Vietnam, which probably appeared in the XIX-century :

Tò vò mà nuôi con nhện, / If a wasp were to raise a spider,
Đến khi nó lớn, nó quyện nhau đi. / When it be grown up, it would leave.
Tò vò ngồi khóc tỉ ti, / The wasp would sit there weeping,
Nhện ơi, nhện hỡi! Mày đi đằng nào. / O spider, my spider! Whither art thou gone?

In fact, the wasp has the habit of killing the mother spider, then bringing the spider larvae back to raise as its reserve food. However, the meaning of the poem is about the fate of adopted children. In old Vietnamese society, well-off families often adopted many children. They have a life no different from servants, and if they are girls, they will be allowed to marry their master's son. Even in my father's family, there are many men whose their parents have arranged for them to get married since birth. Therefore, there are two very funny facts : Both of bride and groom thought each other as brothers or sisters, the groom even carried the bride all day, because they were both just teenagers ; in addition, because family life was so mixed, incest occurs between father-in-law and daughter-in-law (if the husband was too young and the wife was older), mother-in-law and son-in-law, or this person's siblings and the other person's spouse was ever extremely common. That also makes genealogies only reveal half the truth.

When this poem is turned into a song, it contains another meaning, that is sad but more beautiful. Wasp and spider are like a couple who once had beautiful memories together, but then spider left and left wasp an endless sadness. In the song, the wasp counts the threads of spider silk to blame the spider for his ungratefulness. Finally, the wasp got caught in the spider's web and died. It must be added that the silk thread is a very popular literary and musical image in Vietnam, which represents the feelings of a couple when they are apart. The longer the thread, the fuller the nostalgia. If A develops feelings for B, then it is said that A has fallen into B's net.
