There is an actual Chinese steamed pork belly dish named after a famously drunk poet. The dish is called, Dong Po Rou, Dong Po's pork. Su Dong Po was the name of the poet, who is famous in China for being such a great poet, but also being a super alcoholic. So the dish named after him is slow cooked until super soft, almost to the point of being a pudding in texture.
The recipe calls for nearly half the liquid to be wine in some recipes. Also taking quite a while to prepare. But the end result is super soft, like silken tofu but all the porky flavor. You should be able to actually cut the pork with chopsticks. Very delicious I might add. So not all pork belly recipes have a crispy top.
If you are looking for that texture, you want the aptly named, "crispy roast pork". At least if you are going to Chinese restaurant. Just FYI. Also very delicious but with that super crispy top layer of crack, I mean crackling.
