Yu Wanhe, a seven-time winner of culinary competitions, worked incognito at Yunwei Restaurant for six years to repay an old favor to the Zhou family, strictly adhering to the baseline of ingredients and hygiene. When the boss was away, his girlfriend managed the store, and out of jealousy and exclusion of Yu Wanhe, she hired a chef with a forged resume, causing hidden safety hazards with the ingredients and plunging the restaurant into operational difficulties. After resigning, Yu Wanhe was invited to join Gu's Hotel as the executive chef, possessing complete professional decision-making power. Faced with a plea for help from her former employer, she distinguished between gratitude and responsibility, providing limited assistance. In the end, Yu Wanhe founded Artisan Kitchen, promoted ingredient traceability, threw herself into culinary public welfare, and steadfastly adhered to: "What guests cannot see does not mean conscience cannot see it."
