Despite facing repeated obstacles, Lin Zhou and his wife, Su Wan, remain committed to food safety. They insist on preparing their hotpot soup bases by hand every day and using only fresh ingredients.

A bowl of red broth reveals the true nature of people. In business, only those who uphold their conscience can succeed in the long run.
