The Chinese saying is
Above there's heaven
Below, there's Su-Hang ( Soozhou, Hang Zhou ). These were two places where Mandarins built retirement homes with landscaped gardens, read, wrote and practise calligraphy. I could find most things in Hangzhou and they have their own culinary specialities too.
I was there in 1999 in August when it was stiflingly hot - so I gather the summer season , from July- August are very uncomfortable months with few breezes; that the best time might be the autumn and spring seasons and the winter's not too bad either. There's plenty of excellent materials in Hangzhou, huge varieties of Chinese teas and Chinese sweets and delicacies.
When I travel to work in a different country, I like to leave everything, except those of practical uses, behind, like some basic household utensils, comfy clothes/shoes and some sentimental things. A good idea to take food you love - tinned/packaged/dry stuff e.g. bags of preferred brand ground coffee, chocolate, milo, English tea, biscuits, cake and other favourite home food to help you settle down.
I expect you'll find you can get most things in Hangzhou, and plenty of places of such scenic beauty, it might be difficult to leave anything behind eventually.
Wish you a Happy move.
