The line of customers in front of the street food stall is unceasing, and the owner is extremely busy. Mr. Zhou, who has been running his stall for over 30 years, is visited by longtime customers he has known for more than a decade. He specially selects fresh, mother pork without a fishy smell, and sells at least four whole pigs daily. "Freshness, trustworthiness, and fair treatment for young and old" are the principles Mr. Zhou takes pride in as his business philosophy.
