Back to the 80s with a Space, I Become a Tycoon

Back to the 80s with a Space, I Become a Tycoon Plot:

Lin Weiwei, a 21st-century office worker, accidentally returns to a poor family in the 1980s and is bound to a portable space filled with her past-life supplies and practical knowledge. To get rid of the family's hardship, she uses the space to anticipate era trends: from taking scarce supplies to improve life, to doing exclusive business with advanced ideas. Gradually, she becomes a well-known tycoon by selling improved snacks and seizing early business opportunities. She must hide the space's secret, deal with neighbors' rumors and guide her family away from wealth temptation, a retro counterattack story intertwined with family warmth.
