Zhang Ni
The prefecture had an old road that led through Yuexi to Chengdu that was in good condition. But it went through Maoniu territory and was cut off since over a century after that the safe route wasn't good anymore. Zhang Ni sent his attendants to Lang Lu as ambassadors along with generous gifts also asking Lang Lù's paternal aunt to convey his intentions. He offered friendship and expressed his desire to reopen the road. So Lang Lu thereupon led his brothers, wives and children to all go to Zhang Nì swear an oath of alliance, reopen the old road, then a thousand lǐ were cleared and the former relay stations restored allowing communication between Chengdu and the west. Zhang Ni memorialized the court to give a fief to Lang Lu as King of the Máoniúgōupí while Lang Lu sent an envoy to Chengdu to present his formal surrender to Shu. For this exemplary work in the west, Zhang Ni was made General Who Settles Military Affairs with authority over the prefecture as before.
