Over one century ago, Jungli was originally Pingpu aborigines' village. This place was deserted and desolate and full of thorns. Until the Chienlung period of Ching Dynasty, Changchou people of Fuchien Province first crossed the sea to cultivate here. Later people from Fuchien, Kuangtung of the Mainland and the Hakka people followed. All these people made every effort to develop agriculture here and opened for themselves a whole new world.

The original name of Jungli was Jientzuli. In the 50s of Jienlung period of Ching Dynasty, the Ching government established Hsien at Tanshuei and Hsinchu. Chientzuli was located between the two Hsiens, that's how it got this name. Eighteen years before the establishment of the ROC (1894), after the Sino-Japanese Chiawu War Taiwan was ceded to Japan.

Jungli was then ruled by Taipei Hsien and Jungli Administration Office was established. In 1910 Jungli was under the ruling of Jungli Sub-Department of Taoyuan Department, and Jungli Village Administration Office were established. Later it was renamed Jungli District Agency. In September of 1920, the administrative system was changed, Department was abolished and State was established. Then Jungli was ruled by Jungli County of Hsinchu State.

District was changed to Village. In June of 1931, Jungli was upgraded from Village to Street, and renamed Jungli Street Agency. In 1945, Japan was defeated in the Sino-Japanese War and Taiwan was recovered. Jungli was then reassigned to be under the rule of Jungli Town Administration Office.

In October of 1950, it was changed to be under the Taoyuan Hsien. In Feb. 27 of 1967, the Committee of Taiwan Provincial Government passed the change of administrative area and promoted Jungli to become a Hsien-ruled City. Since Jul. 1 of that year, this place was officially renamed Jungli City of Taoyuan County until now.

The development of Jungli City was very difficult. From desolate to prosperous, from Chientzuli to Jungli with 79 basic units (Li), the progress is achieved through sweats and tears of many antecedents. Keeping this in mind, citizens of Jungli should be grateful to ancestors' hardworking, continue to contribute efforts and a earnest heart that loves our own homeland for a better tomorrow of Jungli.
