It could be that you are printing too fast.
If not, then look for mechanical or electrical issues, such as endstops, binding, or electical RF interference.
It would help if you gave us more information, such as whether this is a new thing, or if it has always been happening, etc.
New printer? One you’ve used sucessfully before? etc.
Your request for help should be longer than the required response.

Are your belts tight? You have some layer shifting going on. Also make sure that there’s no binding of either the hotend or bed carriages when they move on the linear rails. Move it by hand to check this. Have you checked the voltages to the steppers?
Thanks perry_1 and jory for your responses. I never printing something perfectly before. I had been dealing with calibration issue before. So you can call it my first printing attempt I already attach you picture, hope you guys can help me to dealing with it. 1. My first tree frog : as you can see it kind of jumping So i try to tighten the belt, but i dont know whether it is tight enough…how you make sure it is tight enough? The other photo are tree frog and marvin at different print speed, as you can see - tree frog doesnt show much difference when i decrease the speed. - marvin shows a big difference although you can see there is still a line where the print shifted before. But in the end my almost perfect marvin was stick off the heated bed. 
Thank you
