Why does the weasel want to pay New Year greetings to chickens, but not to tigers and lions?

The complete sentence of this two-part allegorical saying is that the weasel is not kind enough to pay a New Year call to the chicken. On the surface, the weasel wants to pay a New Year call to the chicken, but in fact it is not so kind. The weasel is the natural enemy of the chicken, thinking that it wants to eat the chicken's meat and make a friendly and harmless appearance on the surface. The purpose is to paralyze the chicken, so that the chicken can hit it with one blow without any defense, and then achieve its own goal. This is ... We know that lions and tigers are kings of the jungle, which is not so easy to deal with. Don't play tricks on them, eat their meat and throw eggs at stones, that is, stealing chickens and wasting rice, not only taking advantage, but also losing your life. The weasel and the lion and tiger are not the same level at all, so there is no comparability and no chance of winning. Therefore, the cunning weasel will not ask for trouble to provoke lions and tigers. Spend the least effort and fill your stomach to survive. In the animal world, it is a jungle world, so the weasel pays New Year greetings to chickens, not to lions and tigers. Do you understand now?
