Taxi-free route: Taoxian Airport-Changke Terminal-Zhangwu-Cullen
You take a taxi to Changke Wharf, which costs about 100 yuan. Then it takes an average of 40 minutes to get to Shenyang-Zhangwu, 28 yuan, and then take a taxi from Zhangwu to Cullen, which is about 85 kilometers, which is estimated to be similar to 200 yuan. I hope to arrive in Karen before 6 pm. The total is about 328 yuan.
If you are not in a hurry, you can go to Fuxin first, then take a bus from Fuxin, and you may get home the next day. But it is the cheapest.
