For my boyfriend's mother, I suggest giving her something healthy and practical to impress her. Don't buy expensive gifts, it will make her think that you don't know how to keep a house. You can send something you need in life, and you can send sesame oil, which is the daily edible oil for the local elderly in Bama, Changshou Township, also known as Changshou Oil. It's appropriate to send this, and it will also make her think that you are good at housekeeping.
