I know bullet train from Tianjin to Beijing. How do I go to Forbidden City after arriving?

First of all, the bullet train will arrve at Beijing South Railway Station. From there, you can take metro line 4 to Xidan Station and take metro line 1 to Tiananmen East Station, Exit A. After arriving, walk south to find the scenic area directly. If by taxi, the cab fare is CNY 30-40 in the day time.
