It depends on how you spend your daily life. If you cook for yourself, 20 yuan/day is enough. If you eat three meals a day, it will cost about 40 yuan/day (fast food costs at least 15 yuan a serving). Renting a single room in a farmer's house costs about 300 yuan per month.

Interning in a hospital should include food and accommodation, right?

If you don’t spend extravagantly eating, drinking and having fun, you won’t spend much money.
