Kunlun Mountains
There is a strong possibility that the name Kunshan is derived from a hill, but which one is controversial. According to an impacted version, the hill is present-day Little Kunshan ("Xiaokunshan") in Shanghai's Songjiang District. The character ("Kun") was the old Chinese name for the Kunlun Mountains. From it developed the Chinese idiom "a jade from Kunlun Mountains", meaning any "outstanding figure". This was applied to Lu Ji and a hill in his hometown was designated as Kun to commemorate him.
