That's the whole point of the initial beginning of these shows, to use stereotypes to create the funny.

Eddie Huang describes it as thus:

"The only way they could even mention some of the stories in the book was by building a Trojan horse and feeding the pathogenic stereotypes that still define us to a lot of American cyclope. Randall was neutered, Constance was exoticized, and Young Eddie was urbanized so that the viewers got their mise-en-place. People watching these channels have never seen us, and the network’s approach to pacifying them is to say we’re all the same. Sell them pasteurized network television with East Asian faces until they wake up intolerant of their own lactose, and hit 'em with the soy. Baking soya, I got baking soya!"
