It is possible to open pre-purchased tickets one month in advance, unless it is a big day<br/>Otherwise it will not be full; direct trains or good time tickets for going in the morning and returning in the afternoon, only when you think about a specific time period will they be in demand. Taiwan's transportation is convenient, and the Ziqiang train is cheaper than the higher-speed rail, so the high-speed rail tickets are only fully booked during the holidays.
Do I need to buy a ticket in advance to take the high-speed train from Taipei to Taichung? It’s not that the tickets are tight, it’s that it’s cheaper to buy early. High-speed rail early bird tickets 28 days in advance, early bird discounts, different time, different discounts, about 20% off or 10% off. In fact, I personally recommend that you do not need to buy in advance. The time for early bird tickets is stipulated. Don’t let yourself go when you go out to play. Besides, the bus and Taiwan Railway from Taipei to Taichung are also very convenient. Although they are slower, they all arrive in the center of downtown Taichung. The high-speed rail needs to take a shuttle bus to get to the center.
