If you want to go to Hongkou, you should take the subway. Line 2 gets off at Longyang Road Station and Lapras Lu Xian Station. This is the most direct method.
But I have to say, Longlu. . . . . . Eat too much. . . . . . . You can experience it later, which is also a kind of enjoyment.
There is also a line to Longyang Road, and there is a Longxin Reed Line next to Longyang Road, which can be transferred to Ludu at Xuejiazhai. When I was lucky, I arrived at school in two hours. When I was unlucky, I waited in the cold wind for half an hour, and Lu Du didn't come. Finally, I learned my lesson, got stuck in time and got on the subway. . . . . .
In fact, there are many lines, as well as Zhang Nan special line and so on. Let's explore slowly ~
You can go to the library for self-study, but I think the classroom is also quite good. I don't understand why everyone likes libraries. . . . .
