Hi. Are you already in Qingdao, or you are coming? Here now the weather is fine, normally around 1-10.c, but should be colder than Mumbai, so better take more cloths, like jacket with you. As for the currency exchange rate, do you use US dollar, or rupees .If US dollar, it's around 1 dollar=6.8 RMB. If rupees, 1RMB=6.75rupees. For foods, if you like seafood, I bet you will love Qingdao. And you can also find a lot of interesting restaurants here. Have a good time in Qingdao!
