What are the economical routes to travel freely to Taiwan Province?

The so-called economical routes are those that use public transport and preferential transportation tickets. The former is to use MRT, passenger transport and buses, while the latter is to buy preferential tickets, such as three-day tickets and five-day tickets for the Taiwan Railway, and a good transport package for Taiwan. Because you didn't mention the exact place you want to go, I'll take Taipei and Kaohsiung as examples. In Taipei, you can use the MRT and Ubike together, which will have a very economical effect in traffic, and then stay in a backpack inn, with a talent of about NT$ 5 yuan every night, and some backpack inns also include breakfast, so that the budget can be saved. As for scenic spots, many scenic spots, such as Danshui and Yangmingshan, are free of charge, so they can enjoy themselves and save the budget. Then, all the money saved can be spent on food. If you are in Kaohsiung, you can also match the MRT and the battery car to expand the 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 (for example, 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 transport, you can have affordable free travel. As for the package of transportation concessions, there are too many kinds, which depends on where you actually want to go, so that you can get an accurate answer. For example, Nantou passenger transport has a package of customs clearance concessions, tickets plus tickets can be discounted, and accommodation in the National Hotel can be discounted. Or the Taiwan Railway has issued a multi-day ticket, which allows you to take the vehicles below the Juguang number unlimited times within a fixed number of days, which is suitable for moving while playing by train. But these are based on the actual itinerary, and there is no way to tell you which discount tickets are available during this trip. The following discount package is a good package if you will stay in Taipei for 2 days. This combination is the MRT from the airport to Taipei twice (you can come and return once each), and the Taipei MRT can be used unlimited times within 48 hours (excluding the Maokong cable car).
