Half a day's time is enough. If you go to the aircraft carrier, you have to play for more than half a day. There is really nothing to see except the Haihe River in Dagu Fort. Not to mention wasting money, it hurts your feelings. I suggest you go to the aircraft carrier to play. You can save the battery for the afternoon and come back to see the Bund. You can see the Bund by boat, and the journey is only 40 minutes. Go to the aircraft carrier first, and take the 459 to Hangu. You can search for other detailed questions. I have answered all the information about the aircraft carrier. If you are not clear, please ask me.
