Wan-li: Year 13, Month 4, Day 10
9 May 1585
It was Imperially commanded that 100,000 liang of silver from the Ministry of Revenue in Nan-jing be sent to Yun-nan. The Regional Inspector Li Ting-yan had advised that the transport of grain rations in Yun-nan was very arduous, and that the transport of one shi of grain required three to four jin [of silver?]. Citing a precedent from the Zheng-tong reign (1436-49), when there was the expeditions against Lu-chuan, he requested assistance from neighbouring provinces. The ministry re-submitted the memorial with a request that the silver be supplied by the Nan-jing Ministry of Revenue, as at this time Hu-guang and Si-chuan were engaged in the extraction of timber.
