I have come to Huangshan many times, the service is standardized once more, and the picker also knows the target price. But the road sign is still unclear, almost took the wrong road, the road sign to the destination is wrong, for example, many signs from Beihai to Guangmingding to Yuping Building are 1.5KM, and the sign after 20 minutes, or 1.5KM is required.
