In the twenty-second year of Yongxing of the Great Liang dynasty, Qinghe County suffers its third consecutive year of severe drought. Crops fail completely, and the Lin family struggles on the brink of running out of food. When four-year-old Xiao Hesui falls and injures herself on a mountain, her blood drips onto a silver lock pendant, unexpectedly awakening her ability to travel between two worlds. She is transported to a modern-day morning market, where she exchanges wild vegetables for rice, flour, and meat. Using modern supplies, Xiao Hesui repeatedly saves her family from desperate situations. She buys medicine and stops the bleeding to save her cousin after he cuts his leg, and sells the carrying baskets woven by her grandfather to secure a steady income. Her grandparents gradually reveal the secret to the whole family. Together, the Lin family weaves baskets, makes cloth shoes, and digs a cellar to store grain, while continuing to pretend to be poor in front of outsiders. (This drama is adapted from the Tomato Novel Four-Year-Old Adorable Girl Xiao Hesui Empties Modern Food Supplies During the Famine.)
