What are the allusions to the courtyard with trees in Houhai and the jade with Jobs in Xia Dynasty?

Legend has it that the use of jade originated in Shang and Zhou Dynasties. Before that, the jade in Xia Dynasty was only used as a stone. Therefore, if you can meet the jade processed in the Xia Dynasty, it is a small probability, which can be used as a witness that the jade began to work. The kind of yard with trees in Beijing Houhai is naturally rare.

A short poem by Feng Tang, "What can be met but not sought"

Original: A yard with trees in Houhai, a jade with work in Xia Dynasty, a cloud at the moment, you in your twenties.
