The Zheng family suffered a similar fate 26 years later at the hands of Yang Ganzhen (楊干貞), who helped found a state named Datianxing (大天興) (928–929).

His successor, Zheng Renmin, attacked Former Shu in 914 but suffered a heavy defeat.

Renmin sent his grand councillor (buxie), Duan Yizong, to Former Shu, possibly to secure a marriage alliance.

In 925, another mission led by the buxie Zheng Zhaochun secured a marriage alliance with Southern Han, whose ruler gave his daughter, the Zengcheng Princess, as wife.

In 927, Later Tang defeated Former Shu and returned thousands of captives to Dachanghe.
