China's two most famous ancient cities, "Beipingyao, South Phoenix", the north is Pingyao Ancient City, the south is the border city Phoenix. Fortunately, I have been lucky to have been there. Unlike the heavyness of the ancient city of Pingyao in the north, the gentleness of the ancient city of Phoenix in the south is more flavorful. Whether sitting on a awning boat, watching the antique hanging tower reflect the Lijiang River, the shadow is more than backwards and swings in circles. Or watching the Lijiang River slowly with the railing in the hanging tower, the green mountains are Yiyi, and time seems to come from Shen Congwen's "Border City".
