If you live in a place where you can cook, it's most economical to cook by yourself. I cook by myself, and I can eat meat for 2 days for 5 yuan, and then I can pack jiaozi, skin for 2 yuan, pork dumplings for 5 yuan, and leeks for 2 yuan to pack 6 jiaozi. It's very economical. Eating instant noodles is actually more expensive than cooking by myself. If you live in a place where you can't cook, it's not necessarily nutritious to save. I'm sorry, I don't know.
