The Confucius Temple is an interesting and different temple. In China you do not find many good condition Confucius temples - each town generally had one and the Cultural Revolution destroyed many of them. This one is the second biggest in China and worthy of some of your time. It is best combined with a visit to the Lama Temple as they are spitting distance from each other.
It is relatively quite there, so you can explore without feeling rushed or claustrophobic.
