A hard-won but not cherished story in history

A story in history that is easy to come by but not cherished:

1, Li Yu, the queen of the Southern Tang Dynasty, easily took over the country from her father, but she didn't know how to cherish, didn't know how to love, became addicted to debauchery dogs, and eventually became the king of national subjugation and became a prisoner.

2. Liu Chan, the master of Shu, died soon after he succeeded to the throne, leaving a joke of "not thinking about Shu".

3. Some corrupt officials in life forget the responsibilities entrusted by the people, greedy for the wrong country, and eventually become prisoners.
