Zheng-tong: Year 7, Month 7, Day 12
17 Aug 1442
Previously, the Jing-yuan Earl Wang Ji had memorialized that the Pu man were causing trouble in the Yong-ping area and thus he wanted to shift the Guang-nan Guard to Yong-ping. At this time, the Yun-nan Provincial Surveillance Commissioner Lai Xun and others advised: "Yong-ping is a very small area and fields are few. Originally there were two independent battalions there and they lacked grain for successive years. If we transfer the whole Guang-nan Guard of over 60,000 men and women, it will be truly difficult to ensure their livelihood." The Emperor ordered that it was not necessary to establish a guard there and that it was only necessary to send some crack troops from the Guang-nan Guard and some officials to manage them on a rotating basis to provide defence. The family members would not have to be moved. As an alternative, troops could be selected from nearby guards and battalions and they could alternate on patrols. The regional commander was ordered to discuss the matter and memorialize, and warned that there must be firm defence on the border and that the troops must not be allowed to lose their place.
