[1] On 23 April 1894, construction was completed and the arsenal, occupying some 40 acres (160,000 m2), could start production of small-caliber cannons.
500,000 taels were spent annually in the arsenal, which constructed Mauser rifles and used steel from the works around Hanyang.
In 1904, the arsenal made several modifications to the design of the Type 88, and, at the same time, expanded production capacity to 50 rifles and 12,000 rounds of ammunition per day.
The quality of the firearms produced in this period was generally low, because the local steel foundries were often ill-equipped and badly managed.
The arsenal, in support of the revolution, switched into full gear and began producing weapons and ammunition day and night.
[citation needed] The Republic of China expanded the arsenal numerous times, and production soared.
