Which counties does Yanshan Mountain in Hebei include?

Yanshan Mountain Range is located at 39 45 ′ ~ 465 438+0 N, 65 438+06 5438+05 40 ′ ~ 65 438+06 5438+09 50 ′ E, which runs east and west and connects with Taihang Mountain to form an "arc mountain range". According to the designated scope, I think from west to east, it should mainly include: Chicheng and Fengning in Zhangjiakou; Luanping, Xinglong, Chengde County, Kuancheng County and Pingquan in Chengde; Zunhua, Qianxi, Feng Run, Qian 'an and Luanxian in Tangshan; Lulong, Funing, Qinglong and Changli in Qinhuangdao.
