I took train from Guangzhou to Shenzhen. We depart from Guangzhou East Railway Station. There are a lot of stations in Guangzhou. If you want to go to Shenzhen via train, make sure you come to this station. Don’t forget to bring passport even you want to have one day return trip because they checked passport before departure.
Once we arrived at Shenzhen, there are a lot of welcome to Shanwei banner. At the beginning it makes me confused because Shanwei is different province. I thought I arrived at wrong station because distance between Shenzhen and Shanwei is 137.85 km. At the end I realized that they were only promotion banners.
