Vitchin stands for Vietnam and China.
I and 7 of my friends started an adventure on September 8 2010 crossing the entire country of Vietnam from South to North by T.R.A.I.N.
We crossed the border of Vietnam and China on F.O.O.T.
... and continued North to Kunming, and then to Chengdu by T.R.A.I.N. again.
If you ask me why, I tell you it was an A.D.V.E.N.T.U.R.E.
If you tell me I'm stupid, I tell you it was F.U.N.
Someday, I'm going to do this A.G.A.I.N.
