What is Bing Xin's hometown mainly about?

I read this essay My Hometown written by Bing Xin with excitement and admiration. I think this article is well written. When I read that "if mine is a big tree, its second generation is branches, and we are the leaves on the branches, the leaves fall to the roots, and our roots are deeply rooted in the fields of Hengling Township, Fujian Province", I felt as if I were there. I also saw them say, "Hengling is a small town and always gets bullied. Now there is an official in the clan who wants to take some soldiers back to boast. " Father is respectful to his ancestors, but he has no soldiers and can't lead troops. "I still remember that the villagers gave their father a gift wrapped in red paper. It was one hundred silver coins, which together were worth ten silver dollars. But he confiscated a penny and went to sacrifice with this officer. This sentence makes me feel that the father in the text doesn't even want ten whole silver dollars. He is really a big man without tears. This reminds me of an old saying, a friendship between gentlemen is as light as water, and a friendship between villains is like wine and meat. I have read couplets indirectly, that is, the boundless scenery and the moon with high weather, the lack of knowledge, right and wrong, and so on. There are also couplets written by my grandfather. I think he is an example for me to learn. I think these couplets are particularly well written. When I finished reading this essay, I seemed to fall asleep, thinking back to my hometown. Although it is not surrounded by mountains on three sides, it is quite satisfactory to me. After reading this article, I finally understand the reason why the author wrote this article. It turns out that it is not only a description of hometown scenery, but also an expression of the author's thoughts and feelings of loving and missing his hometown.
