Great Wall of china?

i have visited . it is great. really vast and long.how abt u?

lenth of great wall is 5000 miles.first established by empirer qingshihuang thousands of years ago to protect china from attack of the northern nomads.today the great wall we visited is generally built in ming period when actually only hundreds of years ago for the same defensive purpose.it worth visit for it is not only a ancient archetectual miracle of human-beings like myriad,but also a symble of china and chinese nation. wish you have fun there,and i'm sure it will never disappoint you.

No i have not visited Great wall of China , but i really like to visit China wall as it can be seen from the moon , well i have seen it only in the picturesS...
