According to what you said, it should be the main campus, which is the old campus, on Chenglin Road in Hedong District. It is very close to get off at Tianjin Station. It can be reached in almost 2 or 3 stops. There are many trains and it is convenient. . Tianjin West Railway Station is much further away. It almost takes an hour without traffic. If you are at Tianjin Station, you can take 666, 827, 906, 836, etc. and get off at Tianjin University of Technology Station. Among them, Tianjin Station 666 is the departure station. You can get on the train at the back square, but be careful not to walk all the way to the square. You should go up from the passage entrance to the middle floor to find the corresponding stop sign in the hall specializing in selling Tianjin local delicacies. Go up the stairs to the back square. If you want to take the bus, it's not expensive and can be reached for about 10-13 yuan. Also tell the driver at the back square to take Xinhua Road, otherwise they will bluff you. If you take the bus, walk back (to the west) for a while after the afternoon, and you will see the south gate of the University of Technology. That gate is not big, haha, it is not as good as the No. 7 Middle School across the way. But it's different when you come in. There are many trees in the school, and this season is the most beautiful. Hope it helps and wish you success.
