According to legend, Wang Anshi, the prime minister of the Northern Song Dynasty, went to Beijing to take the exam when he was young, and his official star was shining high in to be no.1. On the day of the title, the emperor specially invited Qiong Lin Yan to personally summon him! After Wang Anshi tasted the royal banquet, he had a long aftertaste of the royal bones, and the emperor was very happy and gave him a secret recipe. Later, after Wang Anshi was promoted to the first grade, this delicious food was widely spread all over the world. This delicious food was golden in color, tender in chewing, crisp in bone and long in aftertaste. After eating, the index finger remained fragrant, and diners sucked their fingers one after another, which was widely recognized and loved by the general public. The folk called it "finger-sucking ribs".
