What are the economical routes for free travel to Taiwan Province Province?

The so-called economic route is a route that uses public transportation and preferential transportation tickets. The former uses MRT, passenger transport and public transportation, while the latter buys preferential tickets, such as three-day tickets and five-day tickets for Taiwan Railway, and a good transportation package for Taiwan. Because you didn't mention the specific places you want to go, I'll take Taipei and Kaohsiung as examples. In Taipei, you can use MRT and Ubike together, which will have a very economical effect in traffic, and then stay in a backpack inn, which costs about NT$ 500 yuan every night, and some backpack inns also include breakfast, thus saving the budget. As for the scenic spots, many scenic spots such as Danshui and Yangmingshan are free, so you can enjoy yourself and save your budget. Then, all the money saved can be spent on food. If you are in Kaohsiung, you can also use MRT and battery cars to expand your mobile range. The battery car can also be used by two people, saving transportation costs.

There are also many backpacking inns in Kaohsiung, and many scenic spots are free of charge (such as Xiziwan, Qijin and Boer Art Special Zone). In other cities, as long as you refer to the above principles and make good use of public transportation, you can have affordable free travel. As for the package with preferential transportation, there are too many kinds, depending on where you actually want to go, you can get an accurate answer. For example, Nantou passenger transport has a package with preferential customs clearance, and boat tickets can be discounted, and accommodation in national hotel can be discounted. Or the Taiwan Railway has issued a multi-day ticket, which allows you to take the vehicles below Juguang unlimited times in a fixed number of days, which is suitable for playing and moving while taking the train. But these are all based on the actual itinerary, and I can't tell you what discount tickets are available for this itinerary. If you will stay in Taipei for 2 days, the following discount package is a good package. This combination is the MRT from the airport to Taipei twice (you can come once or return once each), and the Taipei MRT can be used unlimited times within 48 hours (excluding the Maokong cable car).
