Yilan City
In 1810 under Qing dynasty rule, a formal administration office was established at Wuwei (五圍) and "Komalan Subprefecture" () was at the present day location of Yilan City. Construction of the city wall was completed a year later. After a few years once the basic infrastructure was ready, the city assumed the political, economical, cultural and educational center for the Lanyang Plain. In 1878, Komalan was a large rice production area commonly called "Kapsulan", and became a district called "Gilan Hsien". It was one of the three new districts that constituted the new Taipeh Prefecture.
