On the eve of the wedding, Song Zhiwei, the lord of Anning County, returned the gold seal in public, gave up his position as princess, and went to Nanling County with only an old oven. She wanted to live an ordinary life by selling biscuits, but she found that the noodle guide left by her mother allowed her to hear the "debt" that the diners dared not mention when they took their first bite. A short piece of cake was brought out by a fake scale, a bag of bitter flour was taken out of the relief grain and disappeared, and the old people from the capital also chased along the grain road. Song Zhiwei didn't want to return to the palace, she just wanted to keep the fire and let the people eat clean food - but when the hunger of the entire county was written into her dough, she had to decide who should guard the lives of ordinary people.
