In p>1942, Henan suffered from famine year after year, and refugees fled to Shaanxi on a large scale. Hao Yulan, who was only ten years old, followed her father and joined the migration army, and settled in the small east gate of the ancient city of Xi 'an. Yulan was forced by life, married Bai Laosi, who was twenty years older than her and had two children, and then gave birth to five children together. Yulan, her seven children and the Henan villagers in Xiaodongmen have been in love with each other for decades. No matter how hard life is, Yulan lives hopefully. She made three wishes to herself: let her kind second grandma enjoy her old age; Open a Henan-style restaurant to make my father useful; Raising children to grow up healthily and lead a good life ... With the changes of the times and the reform and opening up, Yulan's hopes have come true one by one. Yulan and his fellow villagers both found their own happiness. In the 194s, the Central Plains region coincided with the war and famine, and a large number of Henan people moved to Shaanxi to take root. According to incomplete statistics, at present, 1% of the population in Shaanxi Province originated from Henan. According to this history, the TV series "Ye Luo Chang 'an" tells the difficult process of Yulan's family's integration into the city for three generations and 5 years.
