I think your first day&;s trip is mainly in Fangcun (Liwan District) in Guangzhou, so consider living here, mainly around Metro Line 1. It is very convenient to take the subway here in Guangzhou, and you can go where you want to go in three days through the subway.
Of course, it&;s convenient if it&;s go on road trip.
There is no big problem with the schedule of the first day and the second day, and it needs to be adjusted on the third day. Because Huangpu Military Academy is remote, it takes time to drive back and forth, so reserve a half-day trip! Visitors stopped entering at 4: 30 there, so it is more appropriate to arrange it in the morning. In addition, public transportation to Huangpu Military Academy is not so convenient. It is better to rent a car if you can drive. You can rent a shared car, which is cheap and convenient.
In the afternoon, you can go to Pearl River New Town, Guang Zhouta and Red Brick Factory Creative Park. These places are not far apart, and Guang Zhouta is more suitable for going at night.
