In A Dream of Red Mansions, Jia Mu said that steamed mutton with milk is medicine for the elderly and children can't eat it. Why do you say that? Is there a medical basis?

The forty-ninth chapter of A Dream of Red Mansions wrote that the first dish served to grandma on a snowy day was steamed mutton with milk. Grandmother Jia said, "This is the dish of our old people, but it's a pity that you children can't eat it." Therefore, the "mutton" in "steamed mutton with milk" means "never seen the sun", that is, sheep fetus.

Steamed mutton with milk is a dish made of mutton that was not produced during the mother's fetal period as the main raw material, with fresh milk, chicken soup, tremella and other accessories. Several raw materials are rich in nutrition, and have the functions of invigorating qi and blood, treating qi deficiency, nourishing yin and benefiting qi. It is a good product for nourishing the body and is suitable for the elderly to replenish their vitality.

As for what Jia said, "It's a pity that children can't eat it", it's because this dish is spicy, so it's not suitable for young people.
