It is better to save money by cooking at work, because our own income from work is relatively meager. If we always buy rice outside, you will find it particularly expensive, because the prices outside are very high now, and if you eat a little, it will be particularly expensive and you will not have enough to eat. It is very necessary to cook in your own home. You can share with your roommates and cook together, because it will save a lot of trouble. It's enough for two people to buy something, and such things are shared by two people, and the things shared equally are not particularly expensive, so cooking is more economical, which is very suitable for newly graduated college students. Some college students eat instant noodles to save money. It is very harmful to face their health conveniently. Try cooking.
