Well, after 6 years spent in China, I've come to the (late) realization that there is no future for me here.
A decision had to be taken, either stay and go on with my day to day routine that leads pretty much nowhere in a near and far future, or go home and start working for my old days. And give my daughter a decent education where she will not be the foreigner forever.
I have the choice and my friends and family are waiting for me with open arms and opportunities.
So, I' going back. I'll be leaving in 2 weeks, just enough time to pack and say goodbye to all the wonderful people I've met here, and that I will miss. I'll probably come back here every once in a while for holidays. And I'll be on Szs every now and then, just to check that I have nothing to lose by leaving.
