Or go to Zumiao bus station to buy tickets to the provincial station. You can get there directly.
After getting off, it's not far from the west station.
Changing trains is a waste of time and money. I suggest taking a through train.
777 is ok, but it only goes to the pit. You have to change to the subway.
And when there are more than 777 people, there is no place to sit, and you have to spend money to suffer.
