First of all, I think the first reason is that the chef may have some unique secrets when stewing chicken. After all, people are cooks and live by this craft. If there is nothing special, they will definitely not be called chefs. And if you stew chicken at home, you won't have some unique features of a chef, and naturally it won't be more fragrant than a chef.

Secondly, a very important reason is my own psychological problems. No matter what is in daily life, it belongs to others, even if it is the same thing. Therefore, people's psychological self-suggestion, of course, will think that the dishes stewed by chefs are delicious, while the chickens stewed by themselves are not so fragrant. They always think that their chickens will lack something to some extent, but in fact they don't lack anything.

Finally, one of the main reasons is that practice makes perfect. I don't stew chicken every day at home, and I don't cook all the time, so I lack some skills compared with chefs. This is also reasonable, and the result will be no smell stewed by the chef.
