Afa is a Yangshuo local who was born and raised in the area. He took me on a bike tour last week and it was one of the most memorable experiences of my life. He will take you on all the back roads where there are no tourist and you can tour his village and other amazing places you would not see on a regular bike tour. His contact info is email@example.com. If you are looking for an awesome guide and amazing experience this is your guy.
