How to be the first one in the game PUBG(1)

I think the most important things are blood volume and information(where others are).If you want to be the first one,you should avoid fighting.
1.The information about others is more important than box(you can get some things)
many guys serch the box blindly but usually it is dangerous,just like drop box.Because others may find you and kill you when you serch it.You have been exposed.So at this moment ,you prefer to not kill him---unless you have to kill him and it won't expose you.
2.Someone is killed down and he is crawling.If this poor guy is not killed by you,you should judge where is the murderer.Whether we should kill him comletely,we should observe. If we are in the room ,I advise to kill him but in the forest,woshould estimate.Because when we shoot,his friends find us and kill us.
