I have lubricate it often, but it getting more noise this days, So I decide to open the sprocket cover to check it out, It seems it's the time to replace it.
You can *see* the front sprocket is hooked! Replace both and the chain right away
How can it be hooked in the wrong direction, it's the front sprocket that pulls the chain, rather than the chain pulling the sprocket?

I just see hooks and presume it's fooked.

Correct that the front sprocket is pulling the chain,the sprocket rotates in an anticlockwise direction to drive the bike forwards, therfore wear on the sprocket will be on the right hand side of each U or trough of the sprocket......so if the hooking is on the right hand side of the U....... as per pic and hooks are pointing towards direction of travel (anticlockwise) as per pic.......then that sprocket is knackered and a new set n chain is definitely needed!!!!
