how can i reach Beijing World Park from Shahe (Changping District) using subway?

The park is in 158 Dabaotai, Fengtai District and you can use subway to get there, but there are several transfers:

Changping Line (Shahe – Xierqi) – Line 13 (Xierqi – Xizhimen) – Line 4 (Xizhimen - National Library) – Line 9 (National Library – Guogongzhuang) – Fangshan Line (Guogongzhuang –Dabaotai).

After getting off at Dabaotai and leaving from Exit B, you will see the park.

thanks alot Nickson
