Not much inscription for the Khmer peoples' daily life have been recorded, because most of the recorded history we could unconver concerned religion. The Khmer people were very religious and almost all of their buildings were religious monuments.

Daily Life from Literature and Writing
We know that the Khmer king did not own all the land in Ancient Angkor, and rice fields were donated to the temple by large landowners capable of donating their produce to support the kingdom. 'Slaves' were know more as 'Slaves of God', however, they were indeed real slaves, meaning they were owned by a master.
A quote by the Chinese ambassador Zhou Daguan (Chou Ta-Kuan) gives a clear image of slavery.
"Wild men from the hills can be bought to serve as slaves. Families of wealth may own more than one hundred; those of lesser means content themselves with ten or twenty; only the very poor have none."

Daily Life from Carvings and Art
To this day, we can add the demotic bas-reliefs carved on the outher gallery walls of the Bayon at the turn of the 13th Century. This was the one occasion on which the stone-carvers turned from mythological and historical themes to everyday occurences. The combined impression from these bas-reliefs and Zhou Daguan's account is that many of the mundane aspects of Khmer life have remained similar almost to the present day, particularly in the countryside, where houses, markets, ox-carts and so on are almost identical to those carved in sandstone eight centuries ago. However, these few records only afford a glimpse of the society, not its totality.

Writing
The text used were written in Sanskrit or Khmer, and both had equal quantities, but their contents were very different depending on the language used. The Sanskrit texts are poems addressed to the Hindu gods or the Buddha and had a more or less standard format. While the Khmer inscriptions were written inprose and are generally more like an inventory - listing the goods belonging to the gods, such as their land, animals or cult objects.
During the reign of King Rajendravarman a stecil was clearly used for royal insciptions. Then during the reign of King Jayavarman VII, the script took on its characteristic, rather squared up appearance.
