I recall that the old lunch boxes of Factory No. 2 were pre-made dishes.

Prepared dishes refer to being sold to consumers in a form that is easy to store and use after certain processing and processing during food processing. Recalling the production process of the old lunch boxes at the No. 2 Factory, the ingredients went through cutting, cooking, packaging and then freezing or refrigeration to maintain the freshness and taste of the food. This method can improve the shelf life of food and make it easier for consumers to heat and eat it when needed. Therefore, the old lunch boxes from Reminiscence No. 2 Factory are pre-made dishes.
