A total of 21 research papers on salt industry published by Lu Jia-xing. The collection was published in February 1981 as Vol. 21 of the Taiwan Research, an indispensable reference for the study of the history of Taiwan salt industry.
The topics discussed in these papers are four kinds: location examination in ancient salt field, method of solar salt manufacture, salt selling system, and history of salt field in each county and city. At the time of research, there was a great shortage of historical data, and during the period of political martial law, some of the papers were clearly wrong, while others were misinterpreted in accordance with political realities. Indeed there needed to be reviewed.
In this paper, we would like to use newly unearthed historical materials to review Lu’s research on the origin of salt, ancient salt field, method of solar salt manufacture, and salt selling system in Taiwan and try to correct them to give new life. I hope that it can continue to benefit researchers who are interested in the historical of Taiwan salt industry.
