Ma Bingkun, 70, and his wife Chi-wah Lam have been living in Baishan, Jilin. Their five children have flown out of the branches and got married in different cities. Every Spring Festival, a large family will gather in the snowy white mountain. Although the meeting was short, it was also very enjoyable. This year, the forest farm began to snow, and Ma Bingkun's cancer became more and more serious. The sudden death of neighbor Huang Laotai made Ma Lao more worried about his wife's future. After several arguments, the couple finally decided to pay Linzhi Tuo to one of their children and let him take care of them for life. However, on New Year's Eve, for various reasons, the children didn't come back. Looking at the deserted and quiet yard, Ma Bingkun decided to look for it with his wife personally, feeling that he had little time.

The first stop of the old couple is Shanghai where their second daughter Ma Jianchun is located. Unexpectedly, my daughter didn't come to meet her at the station. At this juncture, the old lady got lost again. I finally found my daughter's house, but my daughter's shrewd and mean mother-in-law was rejected by exhausted Ma Bingkun, so the old horse had to find an underground hotel to settle down temporarily. Ma Bingkun, who is worried about his wife and misses his daughter, stayed up all night. The next day, the old horse learned that the old lady fainted at the station and was taken to the hospital. He hurried to the hospital, but fortunately Mrs. Lin was all right. The wife has been found, but the daughter has been lost. Stranger still, no one in her husband's family cares about Ma Jianchun's whereabouts. Why is the relationship between Ma Jianchun and her husband's mother-in-law so cold? Lao Ma decided to find out. It turns out that the stronger Ma Jianchun gave up her stable job in order not to let her mother-in-law look down on her. She has been trying to make a fortune for more than ten years. Now she has not made any money, and even lost her husband's old house. Knowing this, the old couple felt deeply sorry for Ma Jianchun's mother-in-law. They took the initiative to reconcile with her, and at the same time earnestly persuaded their daughter that Ma Jianchun finally woke up. Later, Ma Jianchun and her husband opened a fast food restaurant and lived in a down-to-earth manner.

After solving their eldest daughter's family problems, the old couple took the train to Xi 'an, the city where their eldest son, Ma Jianguo, a Chinese medicine doctor, was located. Ma Bingkun didn't expect that the eldest son took the old couple to a farmhouse in the suburbs. It turned out that the eldest son's family suddenly changed, and his grandson Mark Wen did something illegal. Ma Jianguo had to send his son to prison himself in order to get him back as soon as possible. Therefore, he and his wife Yang can't understand each other and can't go on living. In this way, Ma Jianguo, who lived in Xi 'an for half his life, had to face the embarrassment of separation and nowhere to go. Seeing their son's embarrassment, Ma Bingkun and his wife had to hide their illness and thoughts, and turned to the eldest son's family affairs as a top priority. After successively finding daughter-in-law Yang and grandson, and repeatedly persuading hopeless, the hope of reunifying the country has been dashed. At this time, the landlord and grandson's deep affection for the founding of the people's Republic of China enabled the old couple to find the hope of settling down and building the country. At first, they resisted, but with the active planning of their elderly parents, they gradually accepted their enthusiastic and capable grandson, and they gradually developed feelings. Finally, Sun sold his supermarket and helped open a private clinic.

After leaving safely, the old couple went to Chongqing by train and ship to visit their third son and fourth daughter Ma. Ma Jianhua is driving a BMW, and his sister Qiu Jian is competing to meet the old couple at the dock and help them meet guests in a high-end hotel. During the dinner, I argued with the horse about money, and the old horse took his wife to the hotel in a rage. The next day, the children came to apologize, and the old horse promised to live in each family for half a month.

I live in a villa, and my daughter-in-law Zhu is also enthusiastic and filial. Ma Bingkun is practical. He wants to entrust his wife to his third son. I don't want to. And Zhu are too busy all day to go home to deal with the company's business. Grandson Ma Haotian is withdrawn and only knows how to play computer, so ladies are not popular at all. When I arrived at my daughter Ma's house, my son-in-law Jiang Qiliang was very enthusiastic and the old couple were very moved. The horse was abandoned and married Jiang Qiliang with pregnancy. Not only did he not abandon him, but he also cared about his daughter and granddaughter. But Qiu Jian was not satisfied with Jiang Qiliang's driving a taxi in all aspects. At this time, Wu Guoqing returned to China and became an expert in evaluating the Ma Jianhua project. When he accidentally learned that Ma's daughter was his own child, he tried his best to persuade Ma to divorce and bring her back to him. Ma Qiujian hesitated. Under the design of the old couple, Wu Guoqing only values his children. They let Ma know that Jiang Qiliang is the one who really loves her. The horse suddenly woke up. At this point, something went wrong with Ma Jianhua's project. He made a decision worthy of his conscience and didn't tell his wife Zhu, but it would make him suffer financially. After learning the truth, Zhu felt that her husband regarded himself as a woman who only valued the company and economic interests, so he was disappointed. She filed for divorce. Ma Haotian, a sensitive grandson, therefore ran away from home. The anxious old couple sat in front of the computer in the Internet cafe, waiting for their grandson to appear on the Internet. Through the small camera, they finally found the clue and found Ma Haotian's hiding place. After this change, he Zhu became more aware of the importance of going home. They reconciled, and the crisis of Ma Jianhua Company was successfully solved. Seeing the happy appearance of Hema, the old couple were relieved and boarded the plane to Guangzhou.

The last stop of the two old people was the home of Ma, the youngest son of Guangzhou. Ma Jianxin didn't get married long, his wife Chen was beautiful and gentle, the young couple were very loving, and the old couple's eyes were sweet. The old couple thought that it seems that they can settle in Guangzhou in the future. Unexpectedly, Ma's ex-girlfriend came to the door and said that she was infected with AIDS, so Ma had better go to the hospital for a check-up, which shocked her originally happy life. The old man and Chen decided to hide from the newly pregnant woman and wait for the results of the hospital examination. Under great pressure, Xiao Jian was discovered by Qian Wen, and their feelings fell to the bottom. The day of "sentencing" has finally arrived. The horse was told that he was not infected, and the truth came out. His original name is Xiao Jian, and he has done nothing wrong. Finally, at the wedding, deeply moved Ma and Chen hugged each other tightly.

The old couple who walked more than half of China finally returned to their hometown in Baishan, Jilin. Unfortunately, the old lady Linzhihua in running all the way died unexpectedly. Five children came back to attend the funeral after learning the bad news. Ma Bingkun stubbornly refused his children's proposal to take him to the old age. He said he would keep his wife. Another winter, the old horse came to the old lady's grave as usual. He reported to the old lady that the children were doing well. When it was snowing, Ma Bingkun calmly told his wife to wait patiently and reunite after the Spring Festival.
