Hi Guys
One other thought on potential optional excursions (and budgeting for them). I don't know if it's been re-introduced - it was stopped a couple of years ago due to an outbreak of canine distemper - but, if you get a chance, I would heartily recommend the 'Panda Keeper Experience' at the Chengdu Panda Research Centre (i.e 1-2-1 time with a panda).
Your local guide in Chengdu will tell you if it's available again. If it is, you can only book the day before, numbers are strictly limited and its cash only (in yuan). It's not cheap - around £200 or 2000 yuan back in 2014 when I did it - but absolutely worth every penny. Truly a life affirming experience.
I really hope you get the chance but, if not, the dumpling making workshop is a lot of fun as well.
Have a super trip
