50 and 650 will be fine.
B: You can get off at 678 Hong Kong Road Station on Anshan West Road and walk northeast of Fifth Avenue. Generally speaking, you will go to the east of Fifth Avenue. Chongqing Road, Munan Road, Guangdong Weixian, and Foreign Languages Institute all have many good properties. The west is ok, but I feel that there are not many people going. It's inconvenient to go back without taking 678.
C. it is not convenient to go to the drum tower on Anshan west road. You can take a bus at Liulitai or Qilitai on Weijin Road and get off at Gulou 855. You can walk from Gulou East Street to Guwen Street. There are more than N buses to the department store at the northeast corner station near Guwen Street, two stops away. Peace Road is the exit from the department store, and then you can turn to binjiang road in the middle. It is also suggested to visit Laoxikai Church in Nanjing Road, binjiang road. Take bus No.50 or No.650 from binjiang road Station to Tianjin Railway Station.
