What does the phrase "Jade asks for a good price in the rafters, while women wait to fly in the rafters" mean?

The sentence "Jade asks for a good price in the rafter, while hairpin stays in the rafter" means that both jade and hairpin are put in boxes, hoping to realize its value and play its role one day.

Metaphorically, my current talent shortage is temporary and will soar as long as the time is ripe.

This is what Jia Yucun said in A Dream of Red Mansions. At that time, he was not famous. He recited these two poems to express his incompetence and unwillingness to help others.

Hosta is a precious thing with connotation, but one is in the rafters, that is, the box, the other is in the urn, and it is also in the dressing box. Good things haven't been discovered, so there is such a "good price" and a "waiting for time to fly". Jia Yucun compares himself to Hosta and feels that he is brilliant, but there is no way.
