What is the best way to get to Zhujiajiao from Shanghai Jiaotong University?

There are three different campuses of this university. Since have no idea which one you refer to, I will list all the routes for you.
1. Xuhui Campus: You need to walk southwards to Xujiahui Station of the metro line 9 at first. Then you can take it to Dongjing station, Exit 4. Upon arrival, you may need to walk about 55 yards (50 meters) to the east, and then turn right to Dong Jing Bus Stop, South Jiasong Road. Afterwards, you can take Songzhu Express to Zhujiajiao Station.
2. Minhang Campus: You need to walk eastwards for about 220 yards (200 meters) to the metro line 10 first. Then take it to Laoximen Station and transfer line 8 to Lujiabang Road Station. Continue to take metro line 9 to Dongjing Station, Exit 4. As for the rest route, you can refer to the first one.
3. Minhang Campus: You need walk 35 yards (30 meters) to the south, and then turn right for about 160 yards (150 meters) to Dongchuan Road Cangyuan Road Bus Stop. Afterwards, you may take Hongqiao Hub bus no.4 to Qibao Bus Stop. After that, walk southeast along Qixin Road to Qibao Metro Station and take metro line 9 to Dongjing Station, Exit 4. The rest route is same to the first one.
