Does anyone know how to explain the rhyme of "calling bones to talk about life"

People with a bone weight of 322 yuan and skilled sexual skills are hard to find when they are old and close to your early years, and gradually have the same financial resources as water; When people reach middle age, they have plenty of food and clothing, and then they gain fame and fortune.

The above explanation: when you are young, it may be difficult for you to succeed in doing things. Sometimes you finally earn a little capital, but soon you lose it like water. But don't give up. When you reach middle age, you will have a good life and start your own business. San Qian is rich in food, clothes, wealth and artistic wisdom.

Easy year is hard to accomplish, and every effort is in vain; Free-flowing water for half a life, and then transported to gold. Interpretation of the above picture: it is difficult to succeed when you are young. Even if you spend a lot of energy, your successful career will fall short because of bad luck. Your life will go by like running water. You can't boast of your success after doing a lot of things, but God won't treat you badly all the time. Thirty years in Hedong, thirty years in Hexi, your career will advance by leaps and bounds in your middle-aged and old age, and you won't lose money!
