Most of the wall here is in its original form, and is not reconstructed like some other sites.
Just to look at the sights in Beijing is an enjoyment in itself. However you get so much more when you start to understand the history behind it, plus some of the reasonings why something was built in a certain manner. For example the moat running through the Forbidden city was put there for a purpose. Fengshui says your home must idealy face south, there must be water in front of you, and a hill behind you. The moat represents the water, as for a hill, there was no hill on the north side of the Forbidden city. That was quickly rectified for the Emporer, as they built one, Jingsang park.
The best way to enjoy Beijing is to have your own personal guide show you the sites. This is where I, Mary Yin am able to help.
