1. Take A2 road to return. The departure station is the civil aviation airport, then take Tongyuan Mountain (Kunming Zoo), get off and turn to No.83 to return, then sit all the way to the middle section of Haiyuan North Road (Guiyan Platinum Industry), get off, and you will see a dome-shaped building on your right, which is the business school.

2. Return by bus No.67, start from Minhang Airport, then take Bailong Road, get off at Shizha Overpass (Bailong Road) and turn to Bus No.70, then sit at the middle section of Haiyuan North Road (Guiyan Platinum Industry) and get off.

3. You can also take bus A2 to Xiaocaiyuan overpass, then get off and turn to bus 70, and get off at the middle section of Haiyuan North Road (Guiyan Platinum Industry), but there are many bus stops at Xiaocaiyuan overpass, so be careful to take the wrong bus.

There are other buses that can get there, but it is very troublesome to transfer three or four times.

In fact, I suggest that it is more cost-effective to take a taxi if there are many things. Take a taxi from the airport to the business school and take the second ring elevated road. Less than half an hour, no traffic jam. The fare does not exceed that of 40 yuan. If the driver at the airport doesn't know, just tell him about Haiyuan Temple or Huangtupo, and he will know.

If you have to take the bus, I think you can consider the first route I provided, because the 83 bus is a big bus, which is spacious and suitable for luggage, while the 70 bus is an old bus, which is relatively narrow. The fare is the same, one yuan. The time taken plus the transfer is estimated to be 1.5 hours.
