How much does it cost to go from Changchun to Changbai Mountain for about 2 days? Is there anything else to play around here?

Take bus No.2 107 or 130, Changbai Mountain is 270 per person, Museum is 40, No.2 bus stays within one standard room 150, Wanfuyuan beef soup rice breakfast 10 yuan/person, and buffet lunch on the mountain is 48 yuan/person. Take a taxi from Erdao Town to Shanmen One-way 60 yuan, where most people eat dog meat or tofu barbecue. 2, 4 people are more cost-effective.
