I want to go from Guilin Airport to Yanshuo tonight. Arriving at 8 pm. Is there still a shuttle bus?

The last direct shuttle bus from Guilin Airport to Yangshuo departs at 20:00. Thus you cannot catch it. For your convenience, just take a taxi or hire a private car to Yangshuo directly. Generally speaking, it would cost CNY 300-350 from Liangjiang Airport. The duration is around 1.5 hours.
