what is the best way to go to Jade hotel, Wangfujing Street& forbidden city from beijing airport Terminal3?

Do you refer to Jade Garden Hotel at Wangfujing area exactly? If so, you can take shuttle bus line 1 to Dabeiyao Station. Then walk to Guomao MTR Station to take MTR line 1 to Wangfujing Station. Get out from Exit C and you can walk to your hotel within around 900m. To the Forbidden City, you can use the same way and get off at Tiananmen East Station along subway line 1 to walk to the destination then.
