On the fourth day, I visited Lunzhou Island in Guilin. The first feeling was that it was clean. Although there were many tourists, there was no rubbish on the ground. The forest coverage rate of the island reached 90%. It was a paradise for people who smoked haze every day. The air was super fresh. Also, catch up with the annual tulip exhibition, happy! Listening to the guide said that this is the best angle to see Elephant Trunk Mountain. It has a 1200-year tour history. It is indeed well-known and recommended.
