Take the expressway from Yangliuqing, or take the ring road, then take the Tianjin-Shijiazhuang expressway, and Shijiazhuang-Taiyuan expressway. But there are often traffic jams at the junction of Shijiazhuang and Shanxi. It depends on your luck. Get off at Taiyuan Expressway, take Dayun Expressway around the city and go directly to Yuncheng. It takes about 9 hours from Tianjin to Yuncheng, 1 100 kilometers.
