However, after the founder of the kingdom, Wang Shenzhi, died in 925, the sons squabbled with one another.

The Yin kingdom was rather small, occupying an area in present-day northern Fujian and southern Zhejiang.

It was bounded by Wuyue to the north, Min to the south and east and the Southern Tang to the west.

Wang Yanxi's general Zhu Wenjin claimed the Min throne.

Wang Yanzheng claimed the Min throne, ending Yin's existence as a separate state, but did not return to Changle; rather, he remained at his base of Jian Prefecture, which Southern Tang besieged later in the year, forcing his surrender.
