Go straight after entering the gate, there is a crossroads (we call it the central turntable) about 200 meters, turn left (south), and go straight for about 150 meters, and you will see a very tall building with science and technology building written on it. There is a relatively short building opposite the Second Teaching Building in Gong Hu, commonly known as the "Second Teaching Building". After entering the hall, there is a floor plan, which is easy to find.

good luck
