bus to OCT East from Guomao in Shenzhen

Where exactly will I get a bus to OCT east from Guomao station? Also what are the timings of the bus. I asked few people outside Exit B of Guomao station and no one seems to know or maybe they didn't understand what I asked. Could anyone please guide me the exact route along we proper bus stops to reach OCT east. I stay near Zhuzhilin station
