1 and 5a scenic spots have cleaner environment and higher oxygen content than 4a scenic spots. 5a scenic spot has higher greening rate and richer oxygen content, while 4a scenic spot's environmental planning is not as good as 5a scenic spot's.

The traffic route in 2.5a scenic spot is more reasonable than that in 4a scenic spot. 5a Scenic Area has developed transportation tools and lines, which is convenient for tourists to visit and enter.
