When I visited Guilin with one of my customers we spent 3 days in Longsheng to see the rice terraces. This is one of the beautiful area's of China and is a must see place. When you have to travel from Guilin to Longsheng you can travel with taxi or can take buss. Buss will cost 50 yuan for each person. Longsheng is perfect place for wandering in beautiful environment and beautiful views. But you need good condition because is lot of steep hills. In Longsheng you do not have air pollution. You can enjoy clean air and you will see this is perfect place to loose your stress.
