I am a researcher for Kuliang (Gu Ling), the town where missionaries and others from the Fuzhou area, including Amoy (Xia Men) would take their summer holidays. I have a photo of the Golden Grain award that was given to Mrs. Hartwell, who was
a missionary in Fuzhou during those times. I didn't take a photo of the reverse side of the medal - never thought to! But I am sure this is Mrs. Hartwell's Golden Grain award. It is in the Hartwell files in the Day Mission Library of Yale University.
