We spent the whole morning in a Northeast Park. It was not a day to travel all over the country and the world. The Expo Garden was not a big one, but it was really big. We should find our hometown before entering the park. It's not bad to pack a battery car. 100 yuan an hour, you can make a family of three, 50 yuan an hour for an electric motorcycle, only one person, 30 hours for a bicycle, 20 yuan for a tourist car, four times for a person, two tickets for a person is enough.
