Going to which train station? Is it close to the scenic spot?

If you live near Xizhimen, take the subway from Beijing Beijiao Station to Goubouxia Station and then transfer to a public bus for less than 30 minutes.
It should be Chaoyang District Railway Station ha! Happy Valley is in Chaoyang District.
If staying near Xichuan Gate, take the subway from Beijing North Station to Old Northern Gateway Station, and then take a bus that takes less than half an hour.
It should be Chaoyang District Railway Station, ah! Happy Valley is in Chaoyang District.
