No matter what your major is, first of all, your destination is Chengdu, so whether by plane or by train, Chengdu is your terminal.
Let's talk about how to get to Jiang 'an Campus from Shuangliu Airport. It's close to the airport Jiang 'an campus, so I suggest you take a taxi, which is convenient and quick. It's about 9 kilometers, but you can't take a taxi to 20 yuan. I would like to remind everyone not to take a black car, so be careful.
Let's talk about how to get to Jiang 'an Campus from North Railway Station. Just a few minutes' walk from the North Railway Station, you can get on the subway 1 line, head for Century City, get off at Century City Station (exit B), and then walk about 30 meters to the Century City Station (bus stop). Visually, you can get off at Jiang 'an Garden Station by taking Bus No.67, and then you can reach Jiang 'an Campus in less than 100 meters.
If you get off at Chengdu East Station, you can take Metro Line 2, get off at Tianfu Square, and then transfer to Metro Line 1. The rest of the way is the same as above.
In fact, there is another way to go to Jiang 'an Campus of Sichuan University, and that is to take the school bus directly to Wangjiang Campus. Because Wangjiang Campus is in the city, it is not far from the station to the school station of Wangjiang Campus. Take the bus to Wangjiang Campus first, and then take the school bus directly to school!
If there are many people, there is another way that is feasible, and that is carpooling. Of course, I'm talking about taking a regular taxi, carpooling from the train station to Jiang 'an campus, and it will be done within four people 100. In fact, a person only needs 20 yuan, which is convenient and fast.
