The phrase "Soup is as delicious as a mother's love for the world" should come from Wang Anshi, a writer and famous prime minister in the Northern Song Dynasty, who praised the intangible cultural heritage delicacy of Nanchang, Jiangxi, for simmering soup in earthen pots. However, this statement is not accurate because Wang Anshi did not explicitly mention this sentence in his works. This should be inferred by later generations based on the description and appreciation of food in his works.
