How is Hangzhou from Shanghai and Guangzhou ? how can I reach Hangzhou from Indonesia ?

From Shanghai, you can go to the Hongqiao Railway Station to take the bullet trains for HZ directly.
From Guangzhou, it is suggested to fly to reach HZ. Or you can choose to take the train, but there are only four trains, T170, K528, K210/K211 and K512.
From Indonesia, you can fly from Jakarta to reach Shanghai and then take the bullet train for HZ.
