thanks for any hints.

Re: Need help on p18 in winter camp geometry blue

P18 is one of the harder problems.  There is a typo in the question (hopefully already corrected, but put here just in case): $G$ in the question should be $F$.  It takes some work, but eventually we want to find the ratio $BF/FC$.

Could you please give some hints on how to find this ratio? thanks

BTW, I found FBD to be identical as AOB and many similar triangles but still got stuck in finding the ratio.
