Abstract
The Ancient Chinese usually had two kinds of ideas for the earth. The first idea, which diffused in the Age of Chan-Kuo, (_??__??__??__??_), was that phenomena in the heaven correspond with those on the earth i. e., a solor eclipse or an appearence of a comet suggested a misgovermment, a flood or an earthquake, and a each part of the globe of the heaven corresponds with a each part of several big countries in China.
According to second ides, which deffused after the first idea, phenomena of the earth, separating from those in the heaven, was used to be explained by the idea of “vigor of the earth”. The earth has “vigor of the earth” in it, which wade all the animals, plants and minerals vigorous. And “vigor of the earth” had many complex belts, people and things which was animated by the act of this vigor but those who were not on those belts were not influenced by this vigor. But the system of these belts was artificially changeable. And it was said that in China there was three main belts of “vigor of the earth” (“Dragon Belt” (_??__??_) etc.). By the idea of Dragon Belt they want to explain historically the rise and fall of Chinese countries, and the other two ideas had remained alive uutil Chin (_??_) dynasty.
