In the Kuang-hsu imperial reign in the Ching dynasty, during the great Chiayi drought, local officials didn't eat meat for three consecutive days, praying to Matsu to bring the seasonal rains. Thus in the Chao Tien Temple in Peikang there is a wooden plaque inscribed, "Waters of Kindness."
光緒時，嘉義大旱，地方官齋戒三日，禱告媽祖而降甘霖，於是北港朝天宮內有御賜「慈雲灑潤」匾額。
