First, take the 10 bus from Samsung University Town to Jintang Station. 10 bus leaves at 6: 30 at the earliest (if there is a taxi at the school gate, it is recommended to take a taxi, which is faster).
Then buy tickets to Wukuaishi Station, which leaves at 6: 30 and leaves every 20 minutes.
It takes about 1 hour to get to Wukuaishi Station, and more than 10 minutes to get from Wukuaishi Station to North Station. Take bus 57 or 80, it's very near.
If we get to the East Station, there is also a through train in Jintang. The earliest train is at 7: 30 and the second train is at 9: 00.
