Question: Where are storage areas placed in the Forbidden City?
About the article "Forbidden City", section "Symbolism".

Candidate passages:
The design of the Forbidden City, from its overall layout to the smallest detail, was meticulously planned to reflect philosophical and religious principles, and above all to symbolise the majesty of Imperial power.
Some noted examples of symbolic designs include:
 Yellow is the color of the Emperor.
Thus almost all roofs in the Forbidden City bear yellow glazed tiles.
There are only two exceptions.
The library at the Pavilion of Literary Profundity () had black tiles because black was associated with water, and thus fire-prevention.
Similarly, the Crown Prince's residences have green tiles because green was associated with wood, and thus growth.
 The main halls of the Outer and Inner courts are all arranged in groups of three – the shape of the Qian triagram, representing Heaven.
The residences of the Inner Court on the other hand are arranged in groups of six – the shape of the Kun triagram, representing the Earth.
 The sloping ridges of building roofs are decorated with a line of statuettes led by a man riding a phoenix and followed by an imperial dragon.
The number of statuettes represents the status of the building – a minor building might have 3 or 5.
The Hall of Supreme Harmony has 10, the only building in the country to be permitted this in Imperial times.
As a result, its 10th statuette, called a ""Hangshi"", or "ranked tenth" (), is also unique in the Forbidden City.
 The layout of buildings follows ancient customs laid down in the "Classic of Rites".
Thus, ancestral temples are in front of the palace.
Storage areas are placed in the front part of the palace complex, and residences in the back.
Approximately south of the HAB behind a high berm is the Engineering Equipment Support Area.
The Engineering support equipment was deliberately placed out of direct line of sight from the HAB during MDRS Crew 34 to contribute to the realism of the analogue simulation.
The electrical generators, Casper and Wendy, are housed here in a wood shed and are filled daily with diesel fuel by the Chief Engineer.
The high clay berm helps to shield the HAB from noise of the electrical generators.
Co-located with the generators are the fuel storage tanks for the propane gas and diesel fuel.
Underground conduits convey the electricity and propane gas to the HAB.
The Engineering Area is the second of two areas at MDRS where it is forbidden by the Safety Rules to wear and use sim suits when performing tasks related to ATV or Generator maintenance.
This is due the near impossibility of getting out of the suit quickly should one accidentally spill fuel or oil on themselves and a fire occurs.
All activities involving fuel and oil are performed "out of sim" for fire safety reasons. 
Weapon storage areas (WSA), also known as special ammunition storage (SAS), were extremely well guarded and well defended locations where United States and NATO nuclear weapons were stored during the Cold War era.
In most situations, the WSA or SAS areas were located inside the perimeter of an army barracks or an air base in NATO territory, but in a few cases they were located deep inside wooded areas and miles away from a military base.
Due to changes in the political landscape, the number of special weapons in Europe has been drastically decreased.
Moreover, the introduction of the WS3 Weapon Storage and Security System has made WSAs obsolete.
At present, few WSAs are still operational as modern day special weapons are stored in the floors of concrete aircraft shelters and placed under 24/7 electronic surveillance. 
PODS has delivered more than one million units, and there are more than 141,000 containers in service.PODS containers are left either in the customers driveway, or in certain areas, on the street, which some local governments require permits or charge fees.
Other towns have passed ordinances stating where the storage units can be placed.
