Guilin railway to North Guilin Railway

Hello, how far (how many minutes) do I need to move from Guilin railway station to North railway station...? is tehere any direct connection or shall i take taxi...? Do you know which level of fare shall I expect...?

We are moving from Zhangjiajie to Yangshuo, in my opinion the fastest are trains Zhangjiajie - Changsha - Guilin - Yangshuo, am I right...?

Best wishes
