I come from yi county, so I think the best route is as follows: take the train to Huangshan (soft sleeper is recommended because of the long time), take the bus from Tunxi to yi county at Huangshan bus station (every 20 minutes, at 6: 00 at the earliest and at 5: 30 at the latest), stay in the county town when you arrive in yi county, go to Xidian in the morning and return to the county town at noon the first day. Live in the county town at night. There are many hotels in the county, including three-star Midtown Villa, four-star Jinling Hotel, and some comfortable school hotels without stars. You can choose for yourself. You can stay anytime. (You can stay at any time except 1 October1Sunday Golden Week. You can go directly to Hongcun the next day. On the way to Hongcun, you will pass through Li Xiu Film and Television City (the shooting place of Legend of Wulin), and you can get off and have fun. The hometown of Sai Jinhua, the four famous prostitutes in China (returning to the garden), then take a bus to Hongcun on the road, have lunch in Hongcun, and then take a bus to Mukeng-Zhuhai (the location of Crouching Tiger, Hidden Dragon). It is recommended to stay in the farmhouse for one night and feel the coolness and tranquility brought by the countryside at night in hot weather. On the third morning, you can take a through train on the highway to Huangshan Scenic Area, so that you can visit the world-famous Huangshan Mountain without looking at the mountains when the Five Mountains return. It is recommended to stay in the mountains for one night, where you can see the sea of clouds and the sunrise, which will make you unforgettable for life. After visiting Huangshan Mountain, take the shuttle bus directly from Huangshan Scenic Area to Tunxi, arrive at Huangshan City and stay in the city. As long as it's not Golden Week, you can stay at any time. There are many hotels and you can stay at any time. At this time, you can visit Tunxi Old Street and enjoy the scenery of the city. Finally fly back to Beijing. Something like this. If I don't think it's enough, or if I have any questions, as long as I know, I will know everything and say everything.
