The flight is at 12 o&;clock on the fourth day, so you will leave at 9 o&;clock, so there is no time to play on the last day. On the third day, it is enough to play in the zoo and circus, so the time to really arrange to visit the places you mentioned is only one and a half days. The suggestions for the first two days of your trip are as follows: get off the plane at 10: 00 on Day1, pick up your luggage and walk out of the airport after 11: 00. If you live near Changlong, you can choose to take the subway or the airport bus. Taking the subway is the most economical way. Take the north extension line of Metro Line 3 at the South Airport Station, transfer to Metro Line 3 at Tiyu West Road Station and get off at Hanxi Changlong Station. The whole journey takes about one and a half hours.
