First of all, look carefully at what hobbies your mom has, and which hobbies are the most central. If you are not sure, you can ask your mom to figure out why she has this hobby and what convenience or benefit it brings her. For example, mom loves reading, cooking, square dancing, table tennis, sports, embroidery, and so on.
Second, start writing around mom's hobby. The first paragraph introduces mom and then leads to her hobby. The second paragraph writes about the reasons why mom has this hobby and what influences she herself has. You can give specific examples. In the third paragraph, write what you think and hope about your mom's hobby. It can be recognition or the process from not quite understanding to understanding. The fourth paragraph in conjunction with their own, talk about their own by mom influenced by the love of reading, sports and so on.
