4. AI double-decker bus

Experiencing the local sights and sounds while riding on a sightseeing bus is an easy way to tour the city at a low cost. The artificial intelligence double-decker bus that was recently launched in Shanghai has now made this mode of travel even more attractive.

Instead of having to rely on tickets, tourists can now get on the bus using facial recognition, while high-tech devices on the bus provide a variety of services for tourists, including translating multiple languages and answering questions.

The two bus routes available cover most of the city's sightseeing spots, including the City God Temple, Yu Garden, Shanghai Tower and the Bund. Tourists can buy their one-day passes for the bus for 30 yuan ($4.5) or two-day passes for 50 yuan.
