Bus route from HaGongDa bus stop to HaDongzhan (Harbin East Railway Station)

Hello everyone,
could you please tell me which bus number should take from HaGongDa (Local Institute of Technology) to HaDongZhan(City East railway Staton). When I search on this site, the route starts from An Long Street | 安隆街 for bus no 89 and Automobile Gear Factory | 汽车齿轮厂 for bus no 78. So, I want to know, which bus line pass through HaGongDa station, 89 or 78. Please kindly tell me. Appreciate in advance. Thanks you.
