As a most popular scenic spot in China, the per day visitors number was once up to 30,000 in the national day of 2013! This made a big trouble for the park at that time, as such a popular place to go in China, you'd better not to go there in chinese national holiday, otherwise you can only see people mountain and people sea(人山人海)!

And the last thing to remind you is: even the park is close at 5:30pm, but usaully the workers in the park will ask you to take the last sightseeing bus at 4:30 in the park to go down to go down  if you are still at somewhere far from the park , because it is really a big park, it gonna take you quite a long time to visit along the way back. So if you want to visit the whole spots in the park, better to hurry up when visiting.
