Enormous amount of "precipitation data" was found in official documents in Qing Dynasty, preserved in the First Historical Archives of China. It was found that the "precipitation data" are not the so called precipitation but the penetration depth of rain water into the surface soil. With in situ observations and experiments, hence, a relation between precipitation and the penetration depth was established, with which the document data were converted into precipitation data. As the results, it was found that the seasonal variation and areal pattern of precipitation were roughly consistent with those at present. The total amount, on the other hand, has decreased since the early 19th century. It was concluded, however, that for the recent water shortages, the human activities are more responsible than such a climate change.

中国第一历史档案馆保存着大量清代官方文献中的“降水资料”。结果表明，“降水量”并不是所谓的降水量，而是雨水在表层土壤中的渗透深度。通过现场观测和试验，建立了降水量与穿透深度的关系，并将文献资料转换为降水量。结果表明，降水量的季节变化和空间分布与目前的基本一致。另一方面，自世纪初以来，总金额有所下降。然而，得出的结论是，对于最近的水资源短缺，人类活动比这种气候变化更负责任。
