Need advise which bus to take to go to Qintai road from Chengdu airport

Oh, you must refer to Wenjun Mansion Hotel. According to your arrival time, you can take airport shuttle bus line 1 to Minshan Hotel. Then just take a taxi to your hotel directly. The fare is CNY10 to CNY15.

Or it is fine to take a taxi to your hotel directly. The distance is about 14 miles. And the fare of the taxi is CNY 50 to CNY 55. :)
