It is the most economical and appropriate for you to come to Shouxian County in Huainan. Shouxian is about 15km away from Huainan. It's near Caijiagang. It only takes about 20 minutes to come by bus. After arriving in Shouxian County, you can climb the city wall by rickshaw or on foot from the south gate. From Shuncheng City Wall to the East Gate (Binyangmen), you can overlook the "Feishui Ancient Battlefield" and feel the scene of "nothing happens, trees are full of soldiers". When you get off at the East Gate, you can walk west along East Street and stay at Shouzhou Hotel. After you booked a room, there is an ancient county magistrate in Shouzhou not far away. Chinese food can also be arranged in West Street, which is more economical. After having afternoon tea, you can take a rickshaw to visit Xiwei Temple in Shouxian County and feel the feeling of Zhao Kuangyin commanding the army here when he is trapped in Nantang and waiting for foreign aid. There is also a food called "rescue". Later, I went to the North Gate (Jinghuaimen) and experienced the important military geographical position of Shouyang throat in Huaishang. Out of the north gate, take the only bus to Fengtai County and get off at Forest Park Station. You can walk or ride a motorcycle to Pearl Spring, which is the medium for the birth of the first piece of tofu. There is also Grandma Temple in Forest Park, with a winding path and pleasant scenery. After going down the mountain, you can have an authentic tofu feast outside the north gate. There are 108 exquisite dishes made of tofu, with complete colors and varieties and unique taste. While drinking a little wine, you can face the sparkling Huaihe River in the sunset, as if the weapons of the Spring and Autumn Period and the Warring States Period were shining everywhere. After dinner, strolling along the banks of the antique ancient city will make you feel ethereal and distant, and feel the vicissitudes of history. You are sure to gain a lot.
