Advertising Verse My golden age is long gone, but my silver age is far away. . .

My golden age is long gone, but the silver age is far away...

Is this an advertisement for Wang Xiaobo's book? Because Wang Xiaobo has three novellas, "Golden Age", "Silver Age" and "Bronze Age", they are collectively called the "Era Trilogy". According to this idea, the following may be related to the "Bronze Age". Since I haven't found the source of "My golden age has long gone, but the silver age is far away...", I will try to write two more sentences:

My golden age has long gone,

The Silver Age is far out of reach.

The Bronze Age is deeply buried with the memories of past lives.

Let’s see if we can continue our relationship in this life.
