Question [Q] how do you personalize the lock screen on Hai Pai P6s with Android 4.2.2 OS?

I bought a Hai Pai P6s Chinese Smartphone that has Android 4.2.2 OS. I can't seem to find any personalization options for the lockscreen, menu windows ( can't delete any windows on the sides of my home window) etc. I'm an avid Android device user but not very technical with the different Android OS components. If anyone has any insight please let me know
