Beilun (北仑) is an international port in Zhejiang Province.
Usually, you should take a plane or train to Ningbo, then change the Bus 783, Bus 353(at Ningbo South Railway station), Bus 788 (the fastset one at Younger Stadium) or take a taxi which may cost around ¥100 to Beilun.
Besides Ningbo, one can use Shanghai as a hub to get to Beilun. To travel to and from Shanghai (and access Shanghai's subway system), take a bus from or to Shanghai South Railway Station. As of 2013, the bus fare between Beilun and Shanghai was 115RMB and takes between 3 and 3 1/2 hours. There are about six buses each day between the cities. The first and last buses to Shanghai are at 7:50AM and 3:50PM. The last bus from Shanghai to Beilun is around 4 or 5 PM. It is best to buy a ticket a day ahead if you want to insure a seat at a particular time.
