Firstly, you can easily access to subway, city bus and taxis in Guangzhou, and also internet cafes are scattered in all areas of the city. In a word, you'll find it is easy to move around in Guangzhou. The ferry from Guangzhou is only available along the river and Lianghuashan Port, Nansha Port. There is no ferry at Guangzhou Airport, and also, I have no Idea about this Yulu City you mentioned, where is it?
