The mother passed away shortly after giving birth to the little sister, and the father failed. The twelve-year-old eldest brother Kang Yizheng grew up overnight. In the courtyard deep in the alley, the four children of the Kang family - Kang Yizheng, Kang Yili, Kang Yiming, and Kang Yiyuan depended on each other and struggled to make a living.
The days are like snow in winter, each one covers one another, and one thing covers the past.
The eldest brother successfully entered college, and the life of the Kang family gradually improved. However, the new worries and troubles have never stopped worrying the eldest brother. The studies, emotions, marriage and personal affairs of the younger siblings are like a train that cannot stop, but the happiness of the family is hidden between the rails.
Life is like this. The family has quarrels and quarrels, laughter and tears, but no matter how difficult it is, the Kang family's crooked-necked tree has taken root deep in the alley and is alive with branches and branches.
