1. Itinerary: If you choose a half-day tour, enter the campus from the west gate, visit the Spring Garden, Tsinghua Campus and Auditorium, then return to Gate 2, then take a bus to browse the main building, library area and science college, and finally return to the west gate. This journey will take about 2-3 hours. If you choose a one-day tour, you can enter the campus in the afternoon, stroll around the auditorium area, Tsinghua campus and library area for an afternoon, enjoy the changes of lakes, mountains and trees in the near Spring Garden at night, live in the near Spring Building, stroll around the Science College area the next morning, then go to the central main building area in the east, leave Tsinghua by the main entrance, and finally visit the Tsinghua Science Park. The trip will take about a whole day.
2. Transportation: If you choose a bike or a campus bus, you can move freely on campus, but if you choose a taxi, you may need more time to visit various areas of the campus.
3. Accommodation: If you choose to live on campus, such as near the Spring Building, you can enjoy the night view of the campus at night and have more time to visit the campus. But if you choose off-campus accommodation, you need to spend more time on transportation.
Generally speaking, two hours may not be enough to visit Tsinghua University completely, but if you just visit some major scenic spots, two hours may be enough. If you want to know more about Tsinghua and have more time to enjoy the scenery on campus, then a day trip may be more suitable. When you travel, you need to consider factors such as transportation mode and accommodation in order to arrange your time better.
