Zhang Yang (Fan Wei) is a successful businessman and the boss of a company. He is a bit chauvinistic and opposes his wife Juanjuan (Bai Shan) to start her own business. So the two of them refused to give in to each other and agreed to divorce. The child Douding was awarded to Zhang Yang by the court. This made Douding's grandfather (Zhao Benshan) very anxious. In order to continue to take care of his grandson and live with him, Douding's grandfather disguised himself as a woman and went to his son-in-law's house as a nanny under the pseudonym "Yu Ma". Unexpectedly, Douding's grandfather (Guo Da) was moved by Yu Ma's "gentleness and virtue" and hoped to have a twilight love with Yu Ma. And "Yu Ma" also tried hard to persuade her daughter and son-in-law to remarry. Very warm and funny, look at this family.
