    I kind of think it's fine where it is.

    From this week's Science:

    https://www.science.org/content/article/flood-chinese-graduate-students-stem-was-boon-u-s-students

    Excerpt: “What’s really cool about this study is that it documents, for the first time, how the Chinese government, in growing higher education at home, also contributed in a significant way to the growth of U.S. graduate education, especially at the master’s level in STEM,”

    It may be unlikely that people wish to discuss foreign countries' educational policies here. But if so, the gaokao exam is quite e thing.

    Some species of cuckoos are nest parasites including these:

    How parasitic cuckoos lay host-matching eggs while remaining a single species

    It means they lay eggs in other birds' nests. Eggs hatch and substitute parents do the baby feeding to no benefit of their own. Different bird species eggshells have different color patterns. European cuckoos lay color-matched eggs to that species. Wow moment for me.

    Mrs. Cuckoo could see that other bird from a distance and 'know' it, fair enough. But that isn't egg coloration. Or, could visit the nest with authentic eggs there. Either way, decorating eggs prior to laying seems rather amazing.

    ==
    European cuckoos are modeled into eponymous clocks to announce the hour. It's my understanding that they got this role for being (and calling) common and widespread in Euro forests. Sneaky parents though.

    Are those oxygen bottles a 'thing' there? I haven't seen them in use anywhere I go. Not alpine skiing in Colorado or Mammoth Lakes (variously 2400 - 3900 meters), XC skiing in the lower end of that range, or touristing at top of Pikes Peak or Atacama's Geysers Del Tatio (4300 m). And just last week, closer to you but across the border, not at Tiger's Nest, Paro Taktsang (3100 m), where motorized transport up is not available and everyone was climbing 500 m from the parking lot on their own feet. Slower than at low elevation, but not appearing to need assistance.

    The skiers likely have a different selection bias than the tourists, but everyone had at least overnight acclimation time. When visiting the Mauna Kea observatories long ago, with only an hour's lunch stop to "acclimate" on the drive up from sea level, then quickly bounded up two flights of stairs at the CFHT facility, I did suddenly feel drunk. But that passed quickly and I felt no more symptoms for the rest of the tour.

    A few pharmacies have O2 cans on shelf in Kunming. Commonly sold at tourist destinations above 3000.

    Wow, Taktsang you should post some pictures.
