I hear that citizens of Shanghai speak “Shanghainese,” will I be able to understand them ?
Native Shanghai citizens do speak “Shanghainese,” the local dialect that is vastly different from Mandarin. However, the good thing is that 99% of people under the age of 50 speak fluent Mandarin as well. When you encounter a Shanghainese local, he/she will not attempt to speak “Shanghainese” with you, only Mandarin.
