Longgui Grain Depot, formerly the Wujiang District Longgui Town Grain Storage, contains two grain storage facilities built in different periods, which are products of the planned economy era and hold significant historical value. The renovation and upgrading are based on the grain storage buildings, preserving the characteristics of the grain storage spaces while endowing the old buildings with new functions such as public services, exhibitions and sales, educational training, and library reading. This revitalization drives rural development in the new era with a fresh form, providing residents with a beautiful public space.
