No matter what the gift is, it represents your heart. As long as you have such a heart, your mother will be very happy. Gifts are always light, and affection is the most important. Since you are still a student, it is recommended not to buy expensive things. You can give a bouquet of flowers, which is simple and can add atmosphere to the home.
Or give your mother a new apron, which will make her feel good when cooking every day. You can also go online to see some creative gifts, such as making a set of color-changing cups, one for your father, mother and you, and make your photos on each one. Wouldn't it be warm when drinking water together?
You can also give a crystal music box. Good music will also make your mother very happy.
