  This paper is a continuation of \cite{zhang}, in which we established the
wellposedness result and a comparison theorem for a class of one dimensional
Forward-Backward SDEs. In this paper we extend the wellposedness result to high
dimensional FBSDEs, and weaken the key condition in \cite{zhang} significantly.
Compared to the existing methods in the literature, our result has the
following features: (i) arbitrary time duration; (ii) random coefficients;
(iii) (possibly) degenerate forward diffusion; and (iv) no monotonicity
condition.
