Perhaps since last year, tourists from mainland China (less than 15 people) can go to the queue directly with valid documents without having to make an online reservation in advance. Besides, it won't take long to wait in line on weekdays. Free commentary is available at designated locations and must be admitted before 11:30. The presidential palace has only one floor open for visitors to visit free of charge, while other floors are in the office. Although there are only a few places open for visitors, the architectural design style of the presidential palace is still worth visiting. It is suggested that the visit time should depend on the content of the free commentator's commentary, usually in 30-60 minutes. After leaving the Presidential Palace, after walking for one minute, there is a Presidential Palace Presidential Heritage Exhibition with free tickets. You can visit it together.^^
