Many friends around will go to Sanhe Ancient Town in Hefei to play, but some friends think that many buildings in Sanhe are new and not enough. That's because they didn't really dig into the essence of the Three Rivers. The bluestone road here still preserves the original texture of the historic district and the indelible mark of life of the local people. Like the one-person lane that can only be used by one person, the Zhonghexiang cakes and the former residence of Yang Zhenning, which were sold in Guangxu years, are quite interesting and valuable.
