Helping orphans the way you would do it
Tongling is a city in the Anhui province of China.

In Chinese, Tong means copper, while ling means city. This city produces a great deal of copper and is named after that. Actually, this area has a very long history of copper production, as evidenced from the work of Li Bai, one the most famous poets in Chinese history.
