My trip to Hai Nan on 27-11-08 to 03-12-08:

The air there is very good IF people don smoke...On their busy road you can hear at least 3 horn per min...And on their non-busy road you can see cow and goat on their way to work or home...hahaha...it IS something you can't see in Singapore...The beach there is very beautiful and clean...Nothing much to buy there except for coconut's product...=D
