Three days are too tight. If you have a good car and can run fast, you can visit a few more places. I have driven to several places myself and feel that time is very tight. I would like to give you a suggestion to go to Changjin first. Expressway, then take the Jinji Expressway to Luoyang, after seeing the peonies, go to the Longmen Grottoes, then drive to the Shaolin Temple to have a look, you can also go to Xinzheng New District in Zhengzhou, and then go to Kaifeng. Finally, go to Jiaozuo Yuntai Mountain to see. Finally, take the Jinjiao Expressway and Changjin Expressway back to Changzhi.
