Do you ask about severe altitude sickness for Duanqiao and Changping Gorges on Meishan Mountain? Do I need to bring oxygen bottles and anti-high-altitude medication with me? Thanks!

My strategy, we will arrive in Chengdu on 21st night and then go shopping. Find a hotel. On 22nd day, take the sightseeing bus up Sichuan Opera Mount Baoping Valley at around noon between 11am-12pm. Then have lunch, spend afternoon leisurely, come back to hotel or youth hostel tonight. The next day (23rd), we will go to Langping Valley of Sichuan Opera Mount and maybe get tired in the evening so will head back down mountain first then return to Chengdu for more fun. If not, we’ll stay on 24th day as well before returning to Chongqing.

Please note that “耍” (hāo) is a verb meaning “to have fun” or “to play around”.
I feel the scenery is great! If I had a chance, I would go again next time! Actually, even if you’re worried about something, there are always rental options anywhere
Different people have different needs, taking high blood pressure medication has no effect in an emergency situation. If you remember correctly, there are also oxygen bars available at the airport where you can buy and use it right away on site. I find that having immediate access to this type of product is useful for me personally.
A family of three, 6 o’clock gathering departure, route during having safety staff on the car explaining pseudoknowledge, so scary enough, we didn’t buy anything anyway, too good!

Differing from person to person, high-altitude medicine taken temporarily is useless. Oxygen not allowed on the plane and I don’t remember incorrectly, you can buy in Chengdu. The guide on board will sell anti-high altitude sickness pills which seemed effective to me.
One family of three, 6 o’clock assembly departure, during the trip has safety personnel board to explain high fallacies knowledge, enough scary stuff, anyway we didn’t buy anything good!
