Book of Liang

The Book of Liang , was compiled under Yao Silian, completed in 635. The book heavily relied on his father, Yao Ca's original manuscript, as his comments were quoted in several chapters. The book is being criticised for its blatant distortions of the history of the ruling family.

The Chinese measure of distance used in the Book of Liang probably corresponds to 77 meters, as is the usage for the Book of the Three Kingdoms and other writings of the period.

The Book of Liang is part of the ''Twenty-Four Histories'' canon of Chinese history.

The State of Wenshen

:"The country of Wenshen is 7,000 li north-east of the country of Wa. Over their body, they have tattoos depicting wild beasts. They have three tattooed marks on their foreheads. The marks are straight for noble people, and they are small for lowly people. The people like music, but are not very generous in spite of their affluence, and do not give anything to strangers. They have houses, but no castles. The place in which their king resides is decorated with gold and silver in a manner of rare beauty. The buildings are surrounded by a ditch, about one cho in width, which they fill with quicksilver. When there is rain, it flows on top of the quicksilver. They have many rare things in their markets. Those who are guilty of a light offence are immediately punished with leather whips. Those who commit crimes punishable by death are made to be eaten by ferocious beasts; if there has been any error, then the ferocious beasts will avoid and not eat the victim. Crimes can also be redeemed through imprisonment without food."

The State of Dahan

:"The people of Dahan are 5,000 li east of Wenshen. They do not have an army and are not aggressive. Their manners are the same as those of the country of Wenshen, but their language differs."
