Haha, that's easy to handle. Take the train to Hefei first, and then take the train from Hefei to Tianzhu Mountain, which is Qianshan County. After getting off at Tianzhu Mountain Railway Station, take a taxi, and the driver will take you directly to the car where you can take calamus. A car is one of those buns. Generally speaking, it is much closer to go from the buried hill than to Yuexi County and then to Acorus calamus. My classmates go this way every time they go home. It's cheap.
