Temple, Mansion and Cemetery of Confucius by Els Slots
What did I think of this WHS? It's very interesting if you are into the history of Confucius and maybe Mencius (just 30 minute by taxi away). Even the birthplace of the Yellow Emperor and the tomb of his son are in current QuFu.
I went to Qufu from Xuzhou unline most people arriving from Jinan. This is the same time by train. I took the taxi to the cemetary first and walked there for about 90 minutes in the morning. nice fresh air, quiet. Beautiful area with autumn leaves. (i was there in early November 2015). Then I took an unofficial taxi to the temple and mansion. You can walk it, but it was drizzling...
The temple and mansion are nice to see but not for a first timer in China.
For die hards, the Mencius temple is smaller and less interesting. I did go, just to go and see it. But I would not recommend to most visitors.
Qufu is however a great place if you are traveling the Beijing-Shanghai railway. A nice stop here for a night is worth it.
