Accessing administrative screen or ww.wp.xz.cn

I am not able to understand how can I get access to the administrative screen or panel of ww.wp.xz.cn. Once I access the administrative screen or panel of ww.wp.xz.cn, I want to do the network settings so that I upload content on my ww.wp.xz.cn website with https in the URL or the address bar of my ww.wp.xz.cn website. May I please know how can I perform this action?
