Day 2 in west Sichuan, still have altitude sickness with me, strong headache and sleepy, but when after taking ibuprofen, it relived a bit. 😷 And we are sooooo lucky that we saw the 日照金山/Alpenglow on the Sacred Mountain☀ I would suggest to slow your trip if it is possible, with the altitude over 4000m, it's better to let our body get to used it first then travel or hiking.
