The first half of the sentence regrets fishing for life

Do you regret fishing all your life? There seems to be no such thing. This is just a joke played by future generations, and it can't be true. What it really means should be: If you indulge in fishing, everything else will be abandoned, and you will only regret it for life. But this sentence also has some truth. How can it make sense? This has to start from the source:

As the old saying goes, three years of fishing is poor, and playing with birds destroys life. Once you learn to drive away rabbits, you will never come back. If you love an eagle, you will look up at the sky with tears in your eyes. "Fishing, shooting birds, driving rabbits and playing with eagles" are the four major pastimes of the ancients. Three years of poor fishing can be justified, because ancient materials are scarce. If you indulge in fishing and don't work or study, there will be no food and no pot at home! This will mean that you will have to be poor for three years to recover.

Modern people generally don't say that they will be too poor to uncover the pot because of fishing, but we must understand its ideological core: we can regard it as a hobby, just play it occasionally, and we can't indulge in it. All we care about is fishing, and we will really regret fishing for life.

The above is my humble opinion, I hope it will help you, thank you!
