Thanks for your reply. It has helped me a lot more than all the hours I spent in the previous internet searches I had done until now.

One last thing I would like to confirm: From your post I understand that all these parks (except the one in Tianjin, obviously) are open all the days in June, July and August. Is it correct?

Do you know of any web where I could confirm the inaugurations of the one in Tianjin as soon as it happens?

Yes, it is correct. All of them will open during that time.
I ask one of my Chinese friend for help to check the opening time of the park, so I am not very clear about the website. But he told me that it is said that the park will be open around July.

ok, thanks for the information
