Set in the 1990s, it tells a heartwarming story about two generations who support each other and grow together in ordinary and trivial life, and finally gain family affection, friendship and love. In the distant old days, Xiaoji Street was home to the group of people in our memory. The northern town welcomed the first snow in 1994, and that year Tan Xin and her friends also ushered in their eighteenth birthday. But this beautiful and hurried number did not attract their attention. Instead, it was the marriage of their childhood sweetheart Chen Chen that made the children feel something vaguely - the small team that had been stable for more than ten years, starting from the departure of the first person, they all ran towards their own lives. They stood in front of the door of the eighteen-year-old world with youthful enthusiasm, eager to try, grow wildly, want to run, want to break through, want to grow wings and fly higher and higher, but they did not understand that growing up, like getting old, is the only thing in the world that does not need to be rushed.
