It means there are so many treasures that you can pile them up.
From the poem "Huashan Girl" by Han Yu in the Tang Dynasty: "Take off the hairpin and untie the hoop, and pile up gold and jade."
For example: 1. Growing up in the environment of accumulating gold and jade, she didn't know how much love she got since she was a child. How could she know how to cook?
2. In feudal society, wealthy families piled up gold and jade and lived a luxurious life.
Although his family is in happy ever after, they are very stingy. Also known as "accumulated jade heaps gold".
