Without Spelling Out the Recipe, the Concubine Relies on Pre-Sales to Hollow Out the Capital.

[Main heroine] [Concubine] [Suddenly rich] [Pre-sale] [Reversal] A century-old incense shop has relied on monopolizing secret recipes to control its business. Jiang Zhiyao, who had fled his family and was in trouble, decided to break this deadly rule. She doesn't mix the best fragrances, but customizes sachets with different functions based on the customers' pain points of being afraid of noise and prone to waking up. If the capital is not enough, she pioneers the pre-sale system of paying a deposit and waiting for the goods; if the materials are not enough, she develops a limited repurchase strategy. In just a few months, most of the country was snatched away from Huang Shang. While her rivals are still trying their best to steal the formula, her co-branded stalls have already been opened all over the outskirts of Gyeonggi through the female shopkeeper.
