What are the good routes from Tianjin to go on road trip for a week?

You start from Tianjin and go to Xi 'an. This line is actually quite long. First you have to drive from Tianjin, and then you have to go to Jinci. When you arrive in Shanxi, you can go to Wang Family Courtyard, Pingyao Ancient City and Hukou Waterfall. Then the next stop is Xi 'an. It may take two days to recommend Terracotta Warriors and Huashan Mountain. Then when you come back, you can go to Luoyang to see Longmen Grottoes, and then go back to Tianjin along the route of Yuntai Mountain in Jiaozuo, Zhengzhou.
