I want to travel from Shenzhen airport to ruian city. How? What station to take? please help

There are neither direct rails nor direct flights operating from Shenzhen to Ruian. By rail, you need to get to Shenzhen station in Luohu area first, go to Fuzhou by rail and then to Ruian by a bullet one. Or, you could take a flight to Wenzhou directly and then to Ruian by a bus.
