What a great brother! Your happiness and pride are actually very good gifts. Give him a holiday to rest up. However, it is still recommended to give him a simple gift. Giving him a surprise will also be a kind of encouragement to him. The support of his family is the driving force for his efforts.
However, students of this age have begun to become adults, so the gifts should be more mature and fashionable. It is recommended to give him a new digital product. MP3 is good. It is not expensive and quite practical. There is a kind of crystal product that can be made into a small trophy. Engrave the names and hopes of your family members and put it on his desk. It is also a kind of supervision and encouragement to him from time to time. At the same time, it is also recommended to give your brother a sunshine jar. It can store sunshine and emit light at night. It can bring him some relaxation and warmth when he studies hard. I hope it helps you. Haha.
