I live near Tongzilin and my work is close to the Foxconn plant…
The ride is long and takes a toll on your mind and body after couple of months (70 minutes in the morning and 90 minutes to 2 hours in the evening)
Subway is not ideal either as the factories are atleast 20 minute taxi ride from the Xipu station..
I would recommend to find an apartment close to Qingyang Road,Line 4 (big Metro shopping mall) as it takes less than an hour to go to the plant…
