Tongshan, Xuzhou

Tongshan District, formerly Tongshan County is one of six districts of Xuzhou, Jiangsu province, People's Republic of China, bordering Anhui and Shandong provinces.

History
Tongshan was originally knows as Pengcheng County, the latter merged into Xuzhou during the Yuan and the Ming dynasties, also in the early Qing dynasty. In 1733, as Xuzhou became a prefecture (fu) from an independent department (zhili zhou), its department proper was separated and renamed "Tongshan" (literally: copper-filled hill), which derives from an island in the Weishan Lake.

Tongshan was once the metropolitan county (shou xian) of Xuzhou, thus it referred to the prefecture since 1912, until the Japanese Army captured the county and made Xuzhou City its urban area in 1939.

The county was dissolved in 1952, but was restored in the next year. It became a district since 2010.

In the present day, Tongshan District has 8 subdistricts and 20 towns.
