Can I buy a ticket from Hefei to Quanzhou at Lujiang West Station?

You can't. According to the website of the owner's guide, the manual ticket window of Lujiang Railway Station is in the ticket hall, and the handling fee is 15 yuan. Tickets can be bought at Lujiang Railway Station, but as of August 23, 2023, there is no direct route from Hefei to Quanzhou, so Lujiang West Railway Station can't buy tickets from Hefei to Quanzhou.
