2. Zhongshan Gate Light Rail has no direct bus to Longchuan Road, so you can only transfer to a bus.
(1) You can take bus No.872 at Zhongshan Gate and get off at Children's Hospital.
872 road:
Baiyi Middle School-Jiankai Middle School (formerly Dongli Public Security Bureau)-Dongli Sports Center-Li Xianfeng-Jinmenli-Zhanbinli-Papermaking Dormitory-Zhanzhuangzi-No.2 Bridge-Substation Road-/Kloc-No.0 Bridge-Xincun Building-Zhongshan Gate-No.2 Worker-Dieqiao Apartment-Guanghua Bridge-Tianjin Daily Building (North)-Southwest Building-Sixin
(2) Stay where you are after getting off at Children's Hospital, change to Bus No.48 and get off at Tiantuo Building South.
Xianyang North Road (Xianyang North Road Bus Station)-Benxi Building-Ningcheng Building-No.707 Building-Dingzigu Section 1 1- Qinqin Bridge-Baimiao-Cang Xie Zhuang-Zhangxingzhuang-Yantuo Bridge-Jianchang Road-Minquanmen Bridge-Zengchan Road-Zhengyi Avenue-Changzhou Road-Weiguo Road-Xiangyang Building-Dongfeng
(3) Be careful when crossing the road after getting off the bus, because the speed of rushing off the bridge is fast, so you'd better go first. It's safer to cross the road after the traffic lights. The intersection of the traffic lights is called Baoshan Road.
Afraid of going the wrong way, get off and ask people how to get to Baoshan Road. (Because Longchuan Road is a path, not many people may know it. ) After entering Baoshan Road, the first intersection is Longchuan Road (the right hand side is obviously a delicious Five Blessingg dim sum shop).
Good luck finding it, because it is right in front of my house, so I am familiar with this road. If you still don't understand what I said, leave me a message.
