Mike is one of my foreign friends. If he comes to our country, I shall take him to the Great Wall first. There exist three reasons for my decision.

　　To begin with, the Great Wall symbolizes China ancient history. The Wall built from the 5th century BC until the beginning of the 17th century, experiencing our country's various dynasties.

　　What's more, it embodies our primary principle: teamwork is everything. Obviously, it was rather difficult to build such a wall in the ancient days without any modern machines, because all the work had to be done only by hand. But millions of China people came together and made it a reality.

　　Finally, the Great Wall expresses our determination to resist invasion. The Wall was originally a project of Qin dynasty designed to keep out the invaders. Although millions of people died for building the Wall, China people defended our own sovereignty.

　　I believe that Mike will satisfy with my arrangement.
