what are the good practicess to aware Dukkha
Dukkha is a state in which our expectations differ from the actual state of the world; it's often tied in with a perverse sense of permanence. For instance, it's fairly common for people to assume that their favorite sports team are 'winners'. That produces dukkha when the team loses (because losing violates expectations), and it produces dukkha when the team wins (because winning amplifies the expectation that the team will always win).

Tanhā is a stubborn demand that our expectations must become real; it's usually translated as 'craving,' but... We often see that in super-fans, for instance, who somehow have become so attached to the fortunes of their team that much of their emotional life revolves around it.

All we need to do to be aware of dukkha is to notice when we are discontent with the way things are. If we feel a sour/angry/pissy/grumpy/churlish attitude rising, it's because (somewhere in our head) we expected A from the world and got B. If we feel a pleased/smug/superior/sanctimonious attitude rising, it's because the world momentarily aligned with our expectations, and we damned well think it should do it more often. Tanhā is a bit more difficult to recognize because tanhā usually involves a a self-righteous sense that our expectations are 'real' and the actual state of the world is 'false'; we are so committed to the way things should be that we lose connection to the world as-it-is entirely.

Ridding ourselves of dukkha is advanced practice; it's extraordinarily difficult to live without expectations, and I'm not certain it's realistic or healthy outside of monastic life. Ridding ourselves of tanhā is valid and valuable for all of us, though.
