In Mr. Osman's reply (January 28, 2011; 02:18) to Ms. Eda's question (January 27, 2011; 22:17), Mr. Osman mentioned about MRT Line 3 from the airport, is this line operational already? Can I take the MRT Line 3 from the airport to Guangzhou East Railway station? My flight arrives at 9:30pm and I plan to stay near the Guangzhou East Railway Station.
