Timeline

1. 1451–1457Huai'an Grain Transport Governor-General's Office · JiangsuDuring the Jingtai emperor's reign, against the backdrop of increased northern defense needs after the Tumu Crisis, the Ming court strengthened the Grain Transport Governor-General's authority, implemented fixed quotas for grain boats, and carried out repairs on canal locks and dams, ensuring at least three million shi of grain reached Beijing each year to support frontier garrisons and the capital's civilian food supply.
2. 1457–1460Grand Canal northern-end storage area, Tongzhou · BeijingAfter the Zhengtong emperor's restoration, the Tianshun era continued the Jingtai grain transport framework; the final canal section from Tongzhou to Beijing was dredged and widened, and northern storage capacity was expanded. Grain arriving in Beijing was transferred in batches to the capital's major granaries, supporting the daily consumption of the court and capital troops, and became the core logistics artery sustaining Ming rule in the north.
