Most of the student restaurants in Taiwan universities are outsourced to other manufacturers, and the price will be a little cheaper than if you eat on the street (it’s really only "a little cheaper"..., assuming you eat on the street A meal costs NT$80 in the school, and about NT$70 or NT$75 in the student restaurant), and National Taiwan University is located in the downtown area of ??Taipei Gongguan. To be honest, a meal may cost NT$100.
NTU’s dormitories are considered good among Taiwan’s national universities, but the fees are relatively higher than those of other schools. Generally speaking, living in school dormitories is cheaper than renting a house outside, but it is not absolutely true, because some national universities will also use BOT to build student dormitories. Most of these BOT dormitories are not cheap to live in, and the National Taiwan University you are talking about There are also BOT dormitories. It depends on which one you get. If you rent a house off campus, it will cost about NT$10,000 to NT$12,000 per month.
It is particularly important to emphasize that Taiwan is a capitalist market with a user-pays cost concept. When you come here to study, you cannot only pay for food and accommodation, but also for transportation, books, etc. Dormitory air-conditioning and electricity bills, mobile phone communication fees, Internet fees, mainland student medical insurance fees, etc., and even some campus lectures have to be paid, and the Taiwan government explicitly stipulates that mainland students are not allowed to receive publicly funded scholarships in Taiwan. It is prohibited to engage in any paid part-time job. If you estimate conservatively, it is recommended to prepare more than 4,000 yuan per month as "living expenses".
