Wujiaochang is located in Yangpu District, Shanghai, the full name is "Jiangwan-Wujiaochang", one of the four major city sub-centers in Shanghai, and its southern plot is one of the ten major commercial centers in Shanghai, because of the northeast corner of Shanghai, Shanghai Road, Siping Road, Huangxing Road, Xiangyin Road, The intersection of the five divergent avenues of the road is named. Wujiaochang originally planned the "Great Shanghai Plan" implemented by the Nanjing government in order to break the monopoly of the city center of the Shanghai Concession during the Lib Dem period, and now it is divided into three major sectors, namely the southern business center, the central knowledge innovation center and the northern business center.

When I came, I didn't do a careful strategy. The Pentagon can visit, and there is a visitor center that needs to be reserved 2 weeks in advance. It is a pity that the temporary non-in, the security staff is a standard American soldier, tall and handsome and friendly, repeatedly explained that you have to book on the computer in advance, and there is a big police dog next to you. Very dazzling, the photo person dizzy, I followed the pedestrians forward and walked unknowingly to the office area, met a black official, very politely said that there is no photo here, there is a visitor center to visit. When I left Washington, I saw the Pentagon in full view on the plane, and I was very emotional, really pentagon.

The Pentagon can enter the interior, but you need to make an appointment in advance. Many attractions in the United States provide reservation services. If the appointment is likely not to be your turn, the Pentagon must look down at the height to see the overall effect.

The Pentagon doesn't have much to see, but the 911 victims' stool monument outside the Pentagon is still a bit interesting

There is no place for you to climb to see the Pentagon shape, this is the world's largest single building. Just passing by, can only take a photo from a distance, it is considered to have been. It is nothing to see in the distance, it feels so flat. And, only one corner of the pentagon can be photographed. See the marks of the attack.

Visited the Pentagon 911 Memorial Park. Monuments were erected for all 184 dead. The parallel line on the ground was the line of the plane dive at the time. The trident in the distance was the height of the plane dive. The Pentagon side can still see the difference between the old and new masonry color, the light color stone is the wall repaired after impact. Very shocking!
