Im planning to visit Shenyang this summer like around June or July and I am bringing 2 children...

It will be a bit hot, and the average temp is about 88 – 90 F during these two months, and there are also great deal of rainfall. However, it is safe and fine for your baby. Don’t worry about that.

im in the city at the moment, my wife is from here. We have our 7mt old boy. Im Irish & our boy looks alot like me. Everyone stops to look at the baby westerner. At first it was freaky now we are used to it. It gets hot here & most taxis dont have working aircon. They have a subway here but its new & only have 2 lines at present. The food is awesome & the people are the friendliest iv ever experienced. Some parts of the city look run down but behind those doors are top class apartments. Generally i feel very safe here, buy not knowing what people are saying does unsettel me a little (which is my fault , i should have learned the lingo). enjoy your trip.
