How do I get from Hong Kong to Guangzhou? Is GZ far from Mission Hills?

In Hong Kong, you can take the intercity-through train to GZ.

As I know, the Mission Hill is in Shenzhen. If you want to go there from GZ, you are suggested to go to GZ South Railway Stationt to take a high-speed train to Shenzhen North Station. Then take local subway Longhua Line to Qinghu Station. Then take a taxi to Mission Hills.
Then you can fly from Shenzhen to Weifang and then hire a local taxi to the golf club.
