Excuse me, I want to go to Luoyang from Xuzhou. It is estimated that it will take about 3 days. How to design a better tourist route? What are the scenic spots worth visiting?

I just got back from Luoyang, and I don't know whether you are driving or taking the train. It is recommended to go to Luoyang directly by train, and it is best not to choose Saturday and July. There are too many people. Longmen Grottoes are all tickets 120, and students have a certificate of 60. I didn't go to other places in Luoyang, so it is estimated that there is nothing interesting. Oh, yes, there was a Peony Festival, but I didn't go to see it. It is best not to stay there, because the hotels nearby are very expensive, and the cheapest regular express hotels cost more than 200, which is more than 30% more expensive than many big cities.
