For sightseeing in Guang Zhouta, you can take subway line 3 or APM line and get off at Chigangta Station. There is an exit directly to Guang Zhouta in the subway station. If you want to watch it from the outside, you can leave the station at Exit A of Chigangta Station and look back to Guang Zhouta. I hope it can help you.
