The article is generally reliable and trustworthy as it provides a detailed comparison between two children from different backgrounds. The author provides evidence for their claims by citing examples of the children's behavior in different situations. However, there are some potential biases that should be noted. For example, the author may have a bias towards their own child due to their personal connection with them which could lead to an overly positive portrayal of Ding Qiancheng compared to Ji Xiang. Additionally, the article does not explore any counterarguments or present both sides equally which could lead to a one-sided view of the comparison between the two children. Furthermore, there is no mention of any possible risks associated with either child's behavior which could be important for readers to consider when making decisions about how they raise their own children.
