The story tells that in the early 1990s, Xiaobao, a poor boy in China, followed Bro.Two in the same village and went all the way from the poor and simple northeast countryside to Shenzhen, where the economy was developing rapidly. During this period, the two inadvertently took in a crying baby. How can Xiaobao and his second brother raise the baby? When Xiaobao and her second brother meet Ma Lu, a young woman who is working hard in Shenzhen, what hilarious stories will happen among them? This is the beginning of a history of struggle of small people with mixed smiles and tears and ups and downs.—Ultra-Ghost Police
