前蜀 / Former Shu
Former Shu / 前蜀 is one of the southern/local regimes discussed in EP252 《太平年》之外的五代十国，什么样？. The source presents it as a relatively strong and parallel regime in 十国关系类型 / Ten Kingdoms Relationship Types, rather than as a merely passive fragment outside central history.
The episode also uses 王建 and his family background to show 五代阶层流动 / Five Dynasties Social Mobility: in a violent age, people outside old elite lines could build regimes through military power and local control, even as their successors faced serious inheritance problems.
