How much does it cost to travel freely in Taiwan Province for about 1 days?

Last year, my good friend and I booked a free trip to Taiwan Province, and we spent six days in Taipei. Not counting shopping, we spent less than 4, yuan, and we stayed in a four-flower hotel. If it is normal expenses, it is ideal to spend an average of 8, yuan per person, which does not include some purchases. Two luxurious people will cost about 2, yuan, and one person will. Air tickets and accommodation account for about 6% of your expenses. In fact, the proportion of food in Taiwan Province will not be much, because the price is actually better than that in mainland China, so you should look for air tickets and accommodation first, so that you can almost see how much the budget is.
