As the first dialectal dictionary in our country, Yangxiong’s work Dialect had recorded many dialectal words of Han Dynasty. Through the hard collections and surveys, we have found that the work Dialect showed us a variety of information about the diet culture, the clothes, the medical level and the kinship of Han Dynasty. What have been mentioned above are essential components of a society. Those precious recordings will do us a great favor to get a new point of view and broader sight to study the whole society of Han Dynasty.
