Where does Qishan in Romance of the Three Kingdoms refer to now?

In the romance of the Three Kingdoms, it is said that six people went out of Qishan, not Qishan.

The Qishan you mentioned is the Qishan in Xiqi, Feng Ming in the Romance of the Gods.

Let's talk about Qishan in the three countries:

Qishan is located in the east of Lixian County, Gansu Province, on the north side of the Western Han River. It stretches for about 50 miles, inhaling in the north (now Dabaozi Mountain in Pingquan) and in the east (now Yan Guan Town). Even the mountains are beautiful, and the peak of Luo is majestic. Known as the "Kyushu", the world is magical and the land is embarrassing. The situation controlled the offensive and defensive, so it became a battleground for Wei and Shu in the Three Kingdoms.
