In the 1990s, Qin Shulan returns to the turning point of her life carrying the lessons of her past. To protect her family, she preemptively avoids the dangers her family members face, confronts the outdated mindset at home, and protects her daughter's opportunity to study and go to school. Letting go of a stable job, she seizes the opportunities of the times and starts a business by setting up a street stall down-to-earth. Along the way, she deals with peer competition and intentional harassment from others, resolving crises relying on rules and evidence. While managing her career, she resolves internal family conflicts, runs her life with diligence and wisdom, leads the entire family to strive hard, and reaps the happy life of career success and family reunion.
