Make sure that you have google translator, they don't speak english, they have family package 2 adults and 2 kids for 110 yen, kids under 1.20 m are free, is better to go at night, they have 2 options.
1. Regular elevator.
2.Glass elevator (this is one is a little more expesive but worth it)
They don't have lots of souvenirs and the ones that they have are expensive
But the experience is worth it

The view is nice but very smoggy . You have to pay entrance fee which was about 15euros (17 dollars) for a full price adult ticket (they do discounts for students and families)

Nice your to visit. Great views from the top and almost as pretty to look at from the bottom.

A great place for city views, but had better not to buy sightseeing elevator tickets, it’s not worth.

We went on a cloudy day near sunset, but you can see so far out! It's an excellent view from the top, and they serve you a complimentary beverage during your time at the top. Other than the view and the expensive restaurant below, there's not much else up top. Go during sunset so you can get a night view, and do try to go during sunny weather because the views are much better then.

Amazing 360' view of Chengdu, paid 70 RMB to use the glass lift up and down (one way takes 90 seconds) we would recommend going at a time where you can experience the the beautiful sunset. The tower has an outdoor viewpoint where visitors can stand on a glass floor, an indoor viewpoint as well as a buffet restaurant.
