Hutongs are closely associated with individual four-sided courtyard in which people live. Most Hutongs are running east west for the local dwellers to procure the sunlight. When first started, around 700 years ago, Hutongs were built with the courtyards to the east and the west of the Forbidden City to accommodate high-ranking officials and relatives of the emperors. Afterwards, more were added to the north and south for merchants and common people and these were of a lower standard with lower walls, less or no ornate wood, stone and brick works, and less space.

The Hutongs and courtyards were the connection between the royal family and the outside world. The names for different Hutong are fascinating too; one is called Stinking Leather Hutong (reason can be that some merchants were once processing leather and became quite famous), and another is called Doufu Chen Hutong (reason can be that merchants were once making Doufu or bean curd here and became well-known). It is not only a kind of architecture, but also serves as a window into Beijing folk life and the "encyclopedia of the history and culture of Beijing."
