The May Day self-help tour starts from Dalian and goes to Changbai Mountain.

It depends on whether you want to go to the west slope or the north slope. I work here in Xipo now. You can take the train to Songjiang after 2 pm, and you can go straight to the local train. You can buy a sleeper. You can arrive early the next morning. Very convenient. Hard berth ticket 2 15, soft berth 336. Hard sleeper is good. 10 yuan takes a taxi to Songjiang Town, which is relatively near. When you arrive in Songjiang, if you can afford it, you can choose to stay in Wanda South District (it takes 60 yuan to charter a bus from the railway station to the South District). There are 9 hotels for you to choose from (Westin, Sheraton, Holiday, Hyatt, Park Hyatt, Zhixuan, Ibis, Holiday Suite), all of which are above 3 stars, and the prices are relatively high. You can check the price online first, and then consult the local travel agency. If the budget is low, you can choose to live in Songjiang town. Super 8, Greentree Inn Express, and some small hotels also have it. If you choose a place to live, you can go to Changbai Mountain (the one-person ticket should be 2 10), and it is 150 for Songjianghe Town to take a taxi to the west slope of Changbai Mountain (he will wait for you to go down the mountain and then take you back to your place of residence, and there is a taxi hotline in the local area, which is very convenient), and it should be 3/400 (ticket) for going back to the north slope. I have come back from the north slope of the west slope for a day, and then I will go to Not much to play with. You can check online where Raiders want to play. There are quite a lot of tourists on May Day, and the scenery is OK. Snow can still be seen in Changbai Mountain. If you have any questions, ask me. I have been here for three years, and I can give some advice.
