Four Temples, One Day
So, your challenge is set. Get round all four of Beijing’s sacrificial temples in one day using only public transport. The temples surround Beijing at the four compass points; the Temple of Earth (地坛 Dì Tán) sits to the north of the city, directly opposite the Temple of Heaven (天坛 Tiān Tán), and the Temple of the Sun (日坛 Rì Tán) sits to the east, opposite the tiny Temple of the Moon (月坛 Yuè Tán). The best way to get around is to use the subway system with a little bit of walking, starting at the Sun Temple. Heading counter-clockwise, the journey takes a giant 30km circuit around the capital. This is turbo tourism.
