MAY I KNOW HOW CAN I GO TO THE GREAT WALL AND FORBIDDEN CITY FROM THE BFSU CAMPUS IN BEIJING

To reach Forbidden City, you can walk to reach Weigongcun Station to take subway line 4 to reach Xidan Station and then change to take line 1 to reach West or East Tiananmen Station. Then you can get out of the station and walk to reach the Forbidden City.
To reach Great Wall, you can take the subway line 4 to reach Xizhimen Station and change to line 2 to reach Jishuitan Station. Then you need to get out of station and walk to reach Deshengmen Bus Station to take bus line 919 to reach the Badaling Great Wall.

TQVM Raphe. I really appreciate it.
