I am particularly impressed with Philadelphia. Firstly, Philadelphia has a lot of large parking lots, some of which are as gorgeous as hotels, and the charges are reasonable. We parked in a large parking lot with a sign of $6 an hour. Then we had a wild afternoon and went back to pick up the car at night, and we were drumming in our Hearts - "This is the end of parking. I'm afraid the fee is frightening. But I didn't expect to charge 22 dollars for picking up the car. We were told that the longer the parking time, the cheaper the parking time. Because it's a piecewise pricing method, isn't it? The parking price in this downtown area is much cheaper than that in Beijing. Second, Philadelphia is also a beautiful city with ancient and modern harmony. The Gothic architecture of the old city hall and the modern high-rise buildings live side by side, each with its own splendor. Third, Philadelphia's Chinatown cuisine is better, the temperature is warm and pleasant, the city planning is reasonable, scientific and humane, high-rise buildings are concentrated in downtown, there are no higher buildings around them, so driving in the evening can see a vast expanse of open lights. In addition, Philadelphia is not expensive, and shopping is more casual. I thought Philadelphia had only a Liberty Bell to watch. Who knows the more you play when you arrive?
