Selma adopted Ling in China after discovering that she had reached menopause. She lied about being married to Homer Simpson, in order to fool the Chinese authorities into thinking that Ling would be part of a traditional family as opposed to a single mother. Though she and Jacqueline Bouvier have only been seen once together, Jacqueline is her adopted grandmother.
Ling has aged a couple of years since being adopted and is now a talented child and pretty much everything she does as Patty and Selma push her really hard.[1]
Ling's design was based on the first adopted daughter of Dana Gould, Lulu.[2]
In her first appearance in "Goo Goo Gai Pan", she only made a few appearances making baby giggles and her only actual word in the series was "momma". During her other 3 appearances, she did not talk. She was voiced by Nancy Cartwright, the voice of Bart Simpson, making her the only Bouvier female not voiced by Julie Kavner.
