i did the problem is that they dont factor in the client seed

They do, like I said before. Read their FAQ if you are unable to understand how the client seed affects the result: https://help.bitkong.com/english/provably-fair-game/how-to-check-positions

and i have seen them change it

They do this after you get the new serverseed hash in your own browser (client-side.) This is done in the JS function "generateClientSeed".

That is exactly how they should do it. If they keep the same clientseed for every game, that would be bad.

so that they can easly change and genrate results they deem correct

They cannot change/generate results because you get the hash before the bet and you generate a random clientseed in your browser after getting the hash - which directly affects each result.

.. and the work you did was just saying what provable fair is
there is many many ways to create false provable fair system

There can be indeed some mistakes or possible improvements in a provably fair implementation. For example, if they would generate the client seed serverside or if they send it before the player gets the hash, etc. I have verified many sites on these (small) technical details and found possible improvements for several sites, including Crypto-Games, BetterBets, Rollin, etc. (and they normally improve it quickly.)

After your posts I verified BitKong for the technical details of their provably fair implementation too and my conclusion is that their implementation looks fine.
