First: I will arrive Jan 22nd from ZHUHAI to SHEKOU Ferry Terminal, then I have to take the Airport Express train to Shengzhen. How is fair the ferry station to the rail station? Can I check-in directly or I have to arrive to the airport?

Second: Are there a LINK between Shengzhen Airport to Hong Kong Airport: is a direct connoction or I have to change train? Can I have the web site to visit it?

Many thanks, next Jan 17th is the second time in China and my experience is very low about this country.
