Zhuang Beihe, a veteran chef who has been in the industry for 30 years, was fired because the restaurant completely switched to pre-prepared dishes. Frustrated, he joined the cafeteria of Rainbow Primary School and insisted on using fresh ingredients to fry and cook. With his superb cooking skills, the meals he cooked were loved by children and quickly became popular throughout the school, attracting collective recognition from parents. The supplier of prepared dishes tried to force Zhuang Beihe out of the company after many attempts to obstruct him and poaching him with high salaries, but all failed. He even launched a cooking showdown. In the end, he defeated his opponent with his strength, defended the canteen position, allowed the children to eat meals that were truly hot and warm, and maintained the original intention and dignity of the chef.
