Can I walk from Xizhao Temple Hotel to Temple of Heaven in Beijing? How far is it?

Oh, the distance between these two places is about 2.5 miles. If you want to walk, it's a little bit far.
You can take public bus no. 34 at Guangming Building Station, and get off at Fahua Temple Station. After arriving, walk to the destination directly.
Or you can take a taxi directly. The cab fare is CNY 15 to 20.
