You can take bus No.2 or No.7 and get off at the north gate or east gate of Polytechnic University, but the east gate is closer. Ask any student when you go in. Polytechnic University is very enthusiastic. The opening time of the museum is usually around 8: 00 am-22:00 pm, but it opens on Tuesday morning 10: 00. To get a card, you have to consult the teacher in the library. Go to the canteen to eat, but most canteens use cards, so generally you can ask students to use cards to buy them for you, and you can also give them money. You can go to the West Polytechnic Supermarket and the North Gate to eat. There is a small market outside the north gate, and you will know it when you leave the north gate. There are many students going back and forth there. Wherever they go, follow them. It's very close. You can see them as soon as you get out of the north gate.
