The ancient and modern of Rome

Stepping into ancient Rome, one can particularly understand that 'Rome was not built in a day', similarly, stepping into ancient Rome, one can also feel that 'Rome was not destroyed in a day' either. Today's Rome, the city's architecture still retains its original appearance. Most of the buildings on both sides of the street are five or six-story stone buildings, with huge cornerstones. Small cars are often parked on both sides of the stone road, which is indeed suitable for the small Fiat to shuttle around in the winding alleys. There are very few Asian faces on the street, the shops are not big but quite lively, and the selling prices seem to be quite affordable. Yesterday, I walked through half of the city in several stages, more than 20,000 steps, today I have to rest, my physical strength can't keep up.
