Just stop solving easy problems,and trying harder one.. I start solving hard problems since
year 2010 practicing at    http://poj.org  solving AC<100 problems

and at year 2013 I start solving topcoder Div I 1000pts.. later I found codeforces and start solve fewest AC problems..

There are also some Chinese oj hardest problems is very hard such like

Yeah, solving hard is very helpful, I felt it
At some point I noticed that I am just not able to solve some harder problem
Because it takes very much time to solve
So even if trying whole day then cannot solve
Maybe whole week is enough
But very rarely have an opportunity to solve a problem the whole week
Typical have only three hours per day
But it's at cost of sacrificing important things
So I feel like I cannot improve further

you can choose some easier than hardest problems but harder than medium problems if you don't have enough time to practice
