The profit from fruit wine was substantial, especially in the future. Mrs. Qin was indeed far-sighted. By signing such a contract with her now, one could monopolize her fruit wine business in advance.
It's best to sign it now.
It would be easier than waiting until her fruit wine sells well and then negotiating with her.
Signing such a contract with Fuman Building is beneficial for them, but for her, the disadvantages far outweigh the benefits. Once the contract is signed, it will be like the pig's blood situation from before.
With the pig's blood, Su Yunjin had agreed to sell exclusively to Fuman Building. So, when Young Master Chu came to her last time, with such a contract existing, she dared not sell the method of processing pig's blood to others easily. With this fruit wine, Su Yunjin still wanted to sell it herself and could open a liquor store.
