can you tell me the shadule of train guangzhou to ruian
Even though there is no direct train from Guangzhou to Ruian, you can travel by train to Wenzhou, which is just 25 km or so north of Ruian. There is one train that connects Guangzhou to Wenzhou, K326/327, which departs approximately 11:00 am and arrives around 10:00 am, so that's a train ride of close to 23 hours. You can get on this train at either Guangzhou Railway Station or Guangzhou North Railway Station. Definitely need to get a sleeping berth if you want to go by train. A soft sleeping berth costs about 550 Chinese dollars whereas a hard sleeping berth costs about 350.
There are many trains that go from Wenzhou to Ruian. It's a short trip of 15 minutes if you go by one of these D trains.
Just so you know, you can fly from Guangzhou Baiyun Airport to Wenzhou Yongqiang Airport. There are quite a few daily flights. It costs more - in the range of 500-1,000 Chinese dollars, but flight time is less than 2 hours. There should be hourly shuttle bus from Yongqiang Airport to Ruian (Dongmen Changtu Qiche Zhan - Dongmen Long Distance Bus Station). Bus ride is an hour and half; bus fare 20 dollars or so.
