The large southwestern part of the neighbouring Tiexi District also used to belong to Yuhong District, but in May 2002, the southwestern part of Yuhong District was ceded on order of the city government to establish the Shenyang Economic and Technological Development Zone, and the administration of the region was later transferred to Tiexi District instead. This annexation of land left an exclave territory lying between Tiexi District, Heping District and Sujiatun District, separated from the main body of Yuhong District, hence making the Tiexi District flanked at the "neck" by the two parts of Yuhong.
