I went through Immerqi when I interned in Beijing for 5 months in 2016. They found me a great internship where I felt apart of the team and contributed real work, not busy work that most internships unfortunately hand out. The location of my apartment to my internship and out of work activities was fantastic and made it very easy to explore Beijing. They were always available at any hour of the day when needed and the Immerqi team helps make sure you are settled in. Housing was a little rough as I had to move midway through the 5 months and had a bug infestation at the second apartment, but other than that I have no complaints about my time spent there using Immerqi. I always look back on my time spent there and am excited for my next trip back!
For future participants, make sure that you have information prepared before heading to Beijing, like your phone and getting a Chinese bank account if you are staying there long term. Look up websites to help you find places to go and see so you are already aware of things going on before you get there. At your internship, be apart of your team. Go to lunch with them, hang out outside of work, practice your Chinese with them and let them practice their English with you. To truly understand life in China, you need to befriend Chinese nationals. My coworkers were amazed that I wanted to eat lunch with them when I first started and because of that I was invited to a lot of events that my other foreign friends never got the chance to go to. Be adaptable and open minded, you never know what experiences or invites you will get because of it.
