The more internationally developed cities will have more expats but no matter what city you're in, everyone is in the same boat. They're in a new place and looking to make friends, in general the expat crowd is some of the friendliest people you'll ever meet. Wechat will be your go to for joining group chats related to nightly events, official accounts for promotions, and a lot more. Meetup.com and internations.com is great site that offer a range of events and networking opportunities no matter your interests. Also, just consider your workplace. Your staff and colleague will be your first line of defense for meeting new friends.
