Ah , this computer cant read hanzi so here’s an english post: 

 

some initial thoughts I wrote aftewr just getting back-

 

  The Smell, no people, accents, langauge, different skin colours,  no characters to read, expensive, coins,  signs telling you what you can’t do everywhere, fat people , slang,  quiet, clean air, green, fashion, quaint, not enough staff, too soft bed ,  wealth,  strange music, familiar yet not quite right,  tired, kind of scary, different, interesting, odd, weird,  happy,  insular, authentic, modern and old,  sunny but not hot, safe,  exhausted and  excited!
