What are the main contents, central ideas and writing techniques of Zhang Pincheng's works? Good answer, points!

Main content: Li Liu is a poor and lame boy. Because I lost my parents since I was a child, living alone is difficult, lonely and lonely. By chance, Li Liu met a kind landlord because of a talking myna. These two teenagers, with different identities and great disparity in status, strive to eliminate the estrangement and suspicion between them and become simple friends. However, what they didn't expect was that their friendship would face many tests from the day it was born, and some people even paid the price of blood for it.

Central idea: This set of works holds high the banner of courage, tolerance and idealism, and profoundly expresses the youth friendship, growth sentiment, life feelings and unyielding resistance to feudal thoughts between Li Liu and Fu Qing, a rich young master, aiming at highlighting the strength of masculinity and trying to show the spiritual growth history of contemporary children.

Writing technique: (I don't know if it's incomplete, you can make it up by yourself) I think it's written in the third person, mainly with narrative description.
