The content rating for "大周列国志" APK is suitable for everyone and can be downloaded and installed on Android devices that support API 10 and above.

Regarding the quote, it seems to be a historical or philosophical statement about the impermanence of power and positions in ancient China. Here's a more detailed interpretation:

"In the realm of governance, neither the state of the country nor the roles of the emperor and his ministers are permanent fixtures. This truth has been evident since ancient times. What was once a high bank may become a valley, and what was once a deep valley may become a burial site. Even the surname of the third empress has now changed to that of a concubine!"

>—From "Zuo Zhuan," the 32nd Year of Duke Zhao's reign.

This passage reflects on the transient nature of power and how fortunes can change over time. It suggests that nothing lasts forever, not even the highest ranks in society, as exemplified by the change in status from empress to concubine. The reference to geographical changes (high bank to valley, valley to mausoleum) further emphasizes the idea of constant transformation and the impermanence of all things.
