City tour in half between Xi'an and Weihai

I have been to Weihai. It only takes one night to get from Xi'an to Weihai. You can take a direct train the night before. If you want to reach your destination in about the same time, I suggest you go to Shanxi. There are Pingyao Ancient Town, Qiao Family Courtyard and other tourist attractions, three days is a bit tight. I suggest you consult Xinyada Travel Network and let them help you find a suitable route.
