This region is the main industrial area of Henan Province and rich in coal and non-ferrous metal. Though Luoyang has a rich history, the urban area of Sanmenxia and Pingdingshan were both developed after 1949.
Luoyang and Sanmenxia are on the Longhai Railway and Xulan High-speed railway. The Jiaoliu Railway is across Pingdingshan.
All the three cities can be reached by bus from the other cities in Henan Province.
