Generally speaking, people are not used to the light taste of southerners, and some dishes are sweet. Because northerners have a heavier taste, they don't appreciate the delicious steamed and white-cut.
Northern Chinese don't like to eat boiled chicken in Cantonese cuisine, because they like stir-fried chicken and think it's delicious. They like the taste of spicy chicken or kung pao chicken, so they think that the minced white-cut chicken means that the chef is lazy. In fact, even if they don't eat the original flavor, Cantonese people don't like the flashy stir-fried dishes.
There is also a pine nut fish in Guangdong, which is actually a sweet and sour fish. Few northerners can swallow this dish, because it is sweet and sour, and it is difficult to eat. However, this is the most humble home cooking for children in the south. If mom can cook it, or eat it in a restaurant, she can eat two bowls of rice.
There is also the fact that steamed fish is not loved. Cantonese people think that the best ingredients must be fresh-keeping without adding too much seasoning. Steamed bass, steamed crucian carp, etc., are estimated to be used only by local people.
